Product details
Overview
DRV8906QPWPRQ1 from Texas Instruments is an AEC-Q100 qualified automotive 6-channel half-bridge driver IC for brushed DC motor and solenoid control, operating from 4.5 V to 32 V with 1-A RMS per channel, integrated SPI (5 MHz), programmable PWM generators, and per-channel diagnostics. It enables forward/reverse/brake/coast motor operation in HVAC flap actuators and side mirror systems.
For engineers reviewing the DRV8906QPWPRQ1 datasheet, DRV8906QPWPRQ1 pinout, DRV8906QPWPRQ1 application, or DRV8906QPWPRQ1 equivalent, this page delivers verified electrical specs, thermal metrics, fault-handling behavior, and real-world automotive use context - all confirmed against TI's SLVSEC9C production datasheet.
Technical Context
The DRV8906QPWPRQ1 implements six independent half-bridge output stages with matched high-side and low-side MOSFETs (RDS(ON) = 1.1 Ω typical at 25°C), configurable dead time (2–32 µs), and slew-rate control (0.6–2.5 V/µs). Its 16-bit SPI interface supports daisy-chaining and real-time register access for configuration and fault reporting.
It integrates four 8-bit programmable PWM generators - sufficient for individual channel current limiting or LED dimming - and provides three open-load detection modes (passive, active, low-current) with per-channel diagnostic flags accessible via SPI. Fault conditions including OCP, UVLO, OVP, OTW/OTSD, and enhanced OLD trigger nFAULT assertion and register-flag updates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range (VM) | 4.5 V to 32 V - supports full automotive battery range including cold-crank (4.5 V) and load-dump (32 V) transients. |
| Output current (per channel) | 1-A RMS continuous - enables direct drive of small-to-medium brushed DC motors without external current boosting. |
| RDS(ON) (HS & LS, 25°C) | 1.1 Ω typical - reduces conduction loss and junction temperature rise during sustained 1-A operation. |
| SPI interface | 5-MHz, 16-bit, daisy-chain capable - allows multi-device synchronization and compact microcontroller firmware integration. |
| Sleep current | 1.5 µA typical - meets ultra-low-power requirements for always-on automotive modules with wake-on-SPI or nSLEEP. |
| Thermal resistance (RθJA) | 31.2 °C/W - defines maximum power dissipation limit (≈1.6 W at ΔT = 50°C) for standard 2-layer PCB layout with thermal pad. |
| Operating ambient temperature | –40°C to +125°C - certified for under-hood and cabin-mounted automotive applications per AEC-Q100 Grade 1. |
Pinout & Package
DRV8906QPWPRQ1 uses a 24-pin HTSSOP package (7.80 mm × 4.40 mm) with exposed thermal pad for enhanced heat dissipation. Pin functions are validated per TI's SLVSEC9C datasheet Section 6 (Pin Configuration and Functions) for the PWP variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 13, 24) | Power ground reference | Three dedicated GND pins reduce ground impedance and improve noise immunity across high-current switching paths. |
| OUT1–OUT6 (Pins 2, 23, 14, 11, 3, 10) | Half-bridge output terminals | Each drives one motor winding or solenoid coil; supports H-bridge, high-side, or low-side configurations via SPI control. |
| VM (Pins 16, 21) | Main motor supply input | Dual VM pins enable low-inductance connection to bulk capacitor and reduce IR drop during peak 6-A combined output current. |
| VDD (Pin 6) | Logic supply input | Accepts 3.0–5.5 V - compatible with both 3.3-V and 5-V MCU I/O domains without level-shifting. |
| nSLEEP (Pin 8) | Enable/disable control | Pull-down internal; logic-low entry into 1.5-µA sleep mode - critical for battery-sensitive body electronics modules. |
| nSCS (Pin 19) | SPI chip select | Internal pull-up; active-low enables SPI communication - simplifies bus sharing with other peripherals. |
| SCLK, SDI, SDO (Pins 20, 5, 7) | SPI clock/data I/O | Support 5-MHz operation with defined timing margins; SDO supports daisy-chain readback without additional GPIO. |
| nFAULT (Pin 12) | Open-drain fault indicator | Asserts low on any fault (OCP, UVLO, OTSD, etc.); requires external pull-up - enables system-level fault prioritization. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - ensures reliability in engine bay and passenger compartment deployments. |
| Per-channel diagnostics over SPI | Registers report OCP, OLD, thermal warning, and fault source per half-bridge - eliminates need for external sense resistors or comparators. |
| Configurable PWM generators | Four 8-bit PWM units support independent duty-cycle assignment - enables precise current limiting and smooth LED dimming without MCU intervention. |
| Enhanced open-load detection | Three detection schemes (passive, active, low-current) identify open windings even at <10 mA nominal load - critical for fail-safe HVAC actuator monitoring. |
| Programmable slew rate | Two settings (0.6 V/µs or 2.5 V/µs) balance EMI reduction vs. switching loss - allows optimization for noisy automotive harness environments. |
Applications

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 |
|---|---|---|---|
| DRV8908QPWPRQ1 | 8-channel output, 8 PWM generators, same HTSSOP-24 package and pin-compatible footprint. | Supports two additional half-bridges - suitable when expanding from 6 to 8 motor loads without PCB redesign. | Select when future scalability to 8 loads is required; shares identical SPI protocol, diagnostics, and protection architecture. |
| DRV8910QPWPRQ1 | 10-channel output, 4 PWM generators, same package; OUT9–OUT10 replace NC pins on DRV8906QPWPRQ1. | Enables control of larger actuator sets (e.g., full HVAC + mirror + seat) but reduces per-channel PWM flexibility. | Choose for higher channel count where fewer independent PWMs are acceptable; verify SPI register map compatibility. |
Compared with DRV8906QPWPRQ1, DRV8908QPWPRQ1 adds two channels and PWM units with no layout change, while DRV8910QPWPRQ1 trades PWM count for greater channel density - both retain identical fault handling, thermal performance, and AEC-Q100 qualification.
