Overview
DRV8904QPWPRQ1 from Texas Instruments is an AEC-Q100 qualified 4-channel automotive half-bridge driver IC operating from 4.5 V to 32 V, delivering 1-A RMS per channel with integrated SPI configuration, PWM generation, and comprehensive diagnostics. It drives brushed DC motors or solenoids in HVAC flap actuation and side mirror adjustment systems.
For engineers reviewing the DRV8904QPWPRQ1 datasheet, DRV8904QPWPRQ1 pinout, DRV8904QPWPRQ1 application, or DRV8904QPWPRQ1 equivalent, this page delivers verified electrical specs, HTSSOP-24 package mapping, real-world diagnostic capabilities, and validated alternatives for automotive motor control design.
Technical Context
The DRV8904QPWPRQ1 implements four independent half-bridge outputs with programmable high-side/low-side/H-bridge operation via SPI-configurable PWM generators (8-bit resolution, up to 5 MHz). Each channel features matched RDS(ON) of 0.75 Ω (typ) at 25°C for balanced forward/reverse/brake/coast motor control.
It integrates per-channel diagnostics-including enhanced open-load detection (active, low-current, and passive modes), overcurrent protection with fast OCP response (tOCP specified), VM UVLO/OVP, thermal warning/shutdown, and logic POR-reported via dedicated nFAULT pin and 16-bit SPI register reads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5 V to 32 V VM supply; supports 12 V and 24 V automotive battery rails with 40 V absolute max rating. |
| Output Channels | 4 independent half-bridges; enables dual bidirectional motors or 4 unidirectional loads without external FETs. |
| RDS(ON) (HS/LS) | 0.75 Ω (typ) at 25°C; ensures <1.1 W conduction loss per channel at 1 A RMS, critical for thermal management in sealed modules. |
| SPI Interface | 16-bit, 5-MHz daisy-chain capable; allows single MCU SPI port to configure and monitor multiple DRV89xx-Q1 devices in cascade. |
| Protection Features | Per-channel OCP, VM UVLO/OVP, thermal warning/shutdown, and three-mode open-load detection (active, low-current, passive). |
| Low-Power Mode | 1.5 µA sleep current (typ); reduces parasitic drain in always-on vehicle domains like body control modules. |
| Logic Compatibility | Supports 3.3 V and 5 V logic inputs; eliminates level-shifting for common MCU I/O voltages. |
Pinout & Package
DRV8904QPWPRQ1 uses a 24-pin HTSSOP package (7.80 mm × 4.40 mm) with exposed thermal pad for enhanced power dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 13, 24) | Power ground reference | Three dedicated GND pins minimize ground bounce and improve current return path integrity for all four half-bridges. |
| OUT1–OUT4 (Pins 2, 23, 14, 11) | Half-bridge output terminals | Direct drive outputs for brushed DC motors or solenoids; each supports 1-A RMS continuous current and 6-A peak when paralleled (not applicable to DRV8904QPWPRQ1). |
| VM (Pins 16, 21) | Main power supply input | Dual VM pins reduce IR drop and thermal stress; require ≥10 µF bulk capacitance for stable high-current switching. |
| VDD (Pin 6) | Logic supply input | Accepts 3–5.5 V; requires 0.1 µF ceramic + ≥1 µF bulk capacitor to suppress digital noise coupling into analog/driver sections. |
| nSLEEP (Pin 8) | Driver enable control | Active-low input with internal pull-down; asserts low-power sleep mode (1.5 µA) when deasserted, enabling rapid wake-up (200 µs). |
| nSCS (Pin 19) | SPI chip select | Active-low serial interface enable with internal pull-up; allows daisy-chaining by tying SDO of one device to SDI of next. |
| SCLK, SDI, SDO (Pins 20, 5, 7) | SPI clock/data I/O | 5-MHz capable interface with internal pull-down (SCLK/SDI) and push-pull (SDO); supports full-duplex register read/write for diagnostics. |
| nFAULT (Pin 12) | Open-drain fault indicator | Asserts low on any fault (OCP, OTW, UVLO, etc.); requires external pull-up; enables system-level fault prioritization without polling SPI. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation; meets automotive reliability and stress-test requirements for body electronics. |
| Programmable PWM generators | 8 integrated PWM timers (8-bit duty cycle resolution) configurable per half-bridge for precise current limiting or LED dimming without MCU intervention. |
| Multi-mode open-load detection | Supports active, low-current active, and passive OLD schemes-enables reliable load verification even with microamp-level nominal currents (e.g., small solenoids). |
| Thermal management architecture | Includes thermal warning (OTW) and shutdown (OTSD) with junction temperature monitoring up to 150°C; RθJA = 31.2°C/W enables compact PCB layout. |
| Robust fault reporting | Combines dedicated nFAULT pin alerting with detailed SPI-accessible fault registers (e.g., per-channel OCP source, OLD status, VM condition). |
Applications
| HVAC Flap Actuation | Side Mirror Adjustment |
|---|---|
|
Use Scenario: Precise positioning of HVAC blend and mode flaps in automotive climate control systems. IC Role / Device Role / Timing Role: 4-channel half-bridge driver controlling two bidirectional DC motors-one for blend, one for mode-with independent PWM speed regulation. Use Value: Enables smooth, quiet, and repeatable flap movement using only one IC; integrated diagnostics prevent false stall detection during low-torque transitions. |
Use Scenario: Bidirectional control of side mirror tilt and fold actuators in premium vehicle door modules. IC Role / Device Role / Timing Role: Dual half-bridge configuration driving mirror tilt motor; remaining two channels support fold function or heating element control. Use Value: Reduces BOM count versus discrete FET solutions; low sleep current (<1.5 µA) preserves battery life during vehicle off-state. |
| LED Dimming Control | Small Solenoid Sequencing |
|
Use Scenario: Analog-style brightness control of interior ambient lighting or exterior marker LEDs. IC Role / Device Role / Timing Role: Uses programmable PWM generators to drive LED strings in constant-current mode via external sense resistors and half-bridge switching. Use Value: Eliminates need for separate LED driver ICs; 8-bit PWM resolution provides >250-step dimming granularity without MCU timer overhead. |
Use Scenario: Sequential activation of latching solenoids in seatbelt pretensioners or door lock mechanisms. IC Role / Device Role / Timing Role: Four independent half-bridges energize solenoids with controlled rise/fall times (0.6–2.5 V/µs) to meet mechanical timing constraints. Use Value: Integrated dead-time control (2–32 µs) prevents shoot-through during polarity reversal; passive OLD verifies solenoid coil continuity before actuation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-channel half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8906QPWPRQ1 | 6-channel version with identical 4.5–32 V range, 1-A RMS/channel, and same HTSSOP-24 package; adds two extra OUT pins (OUT5, OUT6). | Required when driving three or more independent brushed DC loads (e.g., HVAC + mirror + seat adjuster) without adding second IC. | Select DRV8906QPWPRQ1 if future design scalability or additional motor/solenoid channels are needed; pin-compatible upgrade path. |
| DRV8908QPWPRQ1 | 8-channel variant with eight PWM generators (vs. eight in DRV8904QPWPRQ1) and expanded open-load detection modes including negative-current OLD. | Suitable for complex body control units requiring simultaneous control of >4 actuators with advanced diagnostics (e.g., trunk lid, fuel flap, hood release). | Choose DRV8908QPWPRQ1 when higher channel density and enhanced OLD coverage justify added cost; shares same footprint but not pin-to-pin compatible. |
Compared with DRV8904QPWPRQ1, DRV8906QPWPRQ1 offers direct pin-compatible expansion to six channels, while DRV8908QPWPRQ1 provides greater diagnostic depth and channel count at the cost of non-drop-in layout reuse-making DRV8904QPWPRQ1 optimal for cost-sensitive, 4-actuator automotive subsystems.

FAQ
What is the maximum continuous current per channel for DRV8904QPWPRQ1?
The DRV8904QPWPRQ1 supports 1-A RMS continuous current per half-bridge channel under recommended operating conditions (TA ≤ 125°C, proper PCB thermal design). Peak current capability is internally limited and depends on thermal margin and pulse width; the datasheet specifies no fixed maximum peak value but confirms safe operation up to 6-A when outputs are paralleled-though that configuration does not apply to the 4-channel DRV8904QPWPRQ1 itself.
Does DRV8904QPWPRQ1 support daisy-chained SPI communication?
Yes, DRV8904QPWPRQ1 supports daisy-chained SPI communication using its SDO (Pin 7) and SDI (Pin 5) pins. When multiple DRV89xx-Q1 devices are connected in series, the SDO of one device feeds the SDI of the next, allowing full configuration and diagnostic readback through a single SPI bus with shared SCLK and nSCS lines-reducing MCU pin count and simplifying firmware.
How does the open-load detection (OLD) work on DRV8904QPWPRQ1?
DRV8904QPWPRQ1 implements three distinct open-load detection schemes: active OLD (drives test current), low-current active OLD (for microamp-level nominal loads), and passive OLD (performed offline with no output drive). These are selectable per channel via SPI registers and enable reliable verification of solenoid or motor coil continuity-even in low-power states-without requiring external circuitry.
What package type and thermal characteristics does DRV8904QPWPRQ1 use?
DRV8904QPWPRQ1 uses a 24-pin HTSSOP package (PWP) with 7.80 mm × 4.40 mm body size and exposed thermal pad. Its thermal metrics include RθJA = 31.2°C/W and RθJC(bot) = 3.1°C/W, enabling effective heat transfer to the PCB. The exposed pad must be soldered to a large copper pour for optimal thermal performance in automotive under-hood applications.
Is DRV8904QPWPRQ1 qualified for automotive safety-critical systems?
DRV8904QPWPRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C ambient), meeting rigorous automotive reliability standards-but it is not ISO 26262 ASIL-certified. It includes functional safety features such as fault reporting via nFAULT and SPI, thermal warning/shutdown, and robust protection circuits, making it suitable for ASIL-B or ASIL-C system integration where the MCU or system controller handles higher-level safety mechanisms.
