Product details
Overview
DRV8962QDDWRQ1 from Texas Instruments is a AEC-Q100 qualified, four-channel half-bridge motor driver IC for 24V/48V automotive body electronics. It delivers up to 5A per channel with 50 mΩ RDS(ON) at 24V/25°C, integrated high-side current sensing (±3.5% accuracy), and independent PWM control per bridge - used in seat actuators, window lift modules, and BLDC motor control.
For engineers reviewing the DRV8962QDDWRQ1 datasheet, DRV8962QDDWRQ1 pinout, DRV8962QDDWRQ1 application, or DRV8962QDDWRQ1 equivalent, key selection criteria include channel independence, 4.5–60V wide supply range, programmable rise/fall time, fault recovery mode (latch-off vs. auto-retry), and thermal performance in HTSSOP-44 package under 125°C ambient.
Technical Context
The DRV8962QDDWRQ1 integrates four independent N-channel half-bridge output stages with charge pump for 100% duty-cycle high-side drive. Each channel features dedicated ENx and INx inputs, enabling static or PWM-controlled operation with automatic dead-time insertion (300 ns) and fast/slow decay selection via input configuration.
Current regulation uses fixed off-time (17 µs) chopping with VREF-adjustable trip threshold and proportional IPROPI outputs (212 µA/A gain). Protection includes VM UVLO (4.23 V rising), OCP (8 A peak), thermal shutdown (150°C), and open-drain nFAULT reporting - all operating across –40°C to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 60 V - supports full 24V/48V automotive battery systems including cold-crank and load-dump transients. |
| Output Current per Channel | Up to 5 A continuous - enables direct drive of solenoids, valves, or brushed-DC motors without external boost stages. |
| RDS(ON) (High/Low-side) | 53 mΩ typical at 25°C - minimizes conduction loss and thermal rise in compact HTSSOP-44 layout. |
| Current Sense Accuracy | ±3.5% at 40–100% rated current - enables precise closed-loop current control using IPROPI analog feedback. |
| Fault Response | Latch-off or auto-retry via OCPM pin - allows system-level fault handling strategy selection without firmware change. |
| Sleep Current | 3 µA typical - meets ultra-low quiescent power requirements for always-on automotive modules. |
| Thermal Resistance | RθJA = 22.2 °C/W - defines PCB copper area and thermal pad design needed to sustain 5A/channel at 125°C ambient. |
Pinout & Package
DRV8962QDDWRQ1 is housed in a thermally enhanced 44-pin HTSSOP (DDW) package measuring 14 mm × 8.1 mm with exposed thermal pad for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCP, CPH, CPL | Charge pump network | Generates gate drive voltage for high-side N-FETs; requires 1 µF (VCP–VM) and 0.1 µF (CPH–CPL) X7R ceramics. |
| VM (Pins 2,11,12,21) | Main power supply input | Connects to 24V/48V battery rail; bypassed locally to each PGND with 0.01 µF + bulk capacitor. |
| PGND1–PGND4 | Per-channel power ground | Separate low-inductance return paths for each half-bridge to minimize crosstalk and improve current sense fidelity. |
| OUT1–OUT4 | Half-bridge output terminals | Each pair (e.g., OUT1/OUT2) forms one H-bridge; pins 4–6, 7–9, 17–19, 14–16 are paralleled per channel for current sharing. |
| IPROPI1–IPROPI4 | Proportional current sense outputs | Source 212 µA/A of high-side current; require external RIPROPI resistor to generate ADC-readable voltage (≤3.3 V). |
| EN1–EN4, IN1–IN4 | Independent enable & PWM inputs | Enable/disable channels (ENx) and set output state (INx); support 0–200 kHz PWM with <2 µs propagation delay. |
| nFAULT, nSLEEP, MODE, OCPM | System interface controls | nFAULT (open-drain) signals faults; nSLEEP enables 3 µA sleep; MODE sets 70/140 ns slew rate; OCPM selects latch/auto-retry. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent half-bridges | Enables simultaneous control of diverse loads - e.g., two DC motors + one solenoid + one TEC - without shared timing constraints. |
| Integrated high-side current sensing | Eliminates need for four external shunt resistors and op-amps; reduces BOM cost and board space while maintaining ±3.5% accuracy. |
| Programmable output slew rate | 70 ns (fast) or 140 ns (slow) via MODE pin - balances EMI reduction against switching loss in noise-sensitive automotive cabins. |
| Dual fault recovery modes | OCPM pin selects latch-off (requires nSLEEP reset) or auto-retry (4.1 ms interval) - matches safety architecture of host ECU. |
| Ultra-low sleep current | 3 µA typical - extends battery life in parked vehicle scenarios where door modules or mirrors remain powered. |
Applications
| Seat Actuator Control | Window Lift Module |
|---|---|
Use Scenario: Precise bidirectional movement of power seat mechanisms using dual brushed-DC motors. IC Role / Device Role / Timing Role: Four-channel half-bridge driver providing independent PWM control and current feedback for position/force monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar four-channel half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8313RTAT | Three-channel, 65V, no integrated current sense outputs; requires external shunts and amplifiers. | Targeted at cost-sensitive 3-phase BLDC only; lacks per-channel enable and IPROPI feedback for multi-load systems. | Choose when only three bridges are needed and current sensing is handled externally - not suitable for solenoid/TEC mixed-load designs. |
| MPQ6532GR-A | Two-channel, 60V, integrated current sense but no programmable slew or OCPM fault recovery selection. | Designed for dual-motor seats/mirrors; lacks fourth channel and flexible fault response needed for trunk/window lift redundancy. | Select for simpler dual-actuator modules where latch-off-only fault behavior is acceptable and fourth channel is unused. |
Compared with DRV8962QDDWRQ1, DRV8313RTAT offers higher voltage margin but omits critical current feedback and channel count, while MPQ6532GR-A provides partial integration yet lacks the configurability and scalability required for complex 24V/48V body control units.

FAQ
What is the maximum continuous output current per channel for DRV8962QDDWRQ1?
The DRV8962QDDWRQ1 supports up to 5 A continuous current per channel at 25°C ambient with adequate PCB copper and thermal pad design. Derating applies above 85°C ambient; full 5A operation requires RθJA ≤ 22.2°C/W and junction temperature maintained below 150°C. The device's 50 mΩ RDS(ON) at 24V enables this rating while limiting conduction loss to ~1.25 W per FET at 5A.
How does the current sense functionality work on DRV8962QDDWRQ1?
DRV8962QDDWRQ1 provides four IPROPI pins (IPROPI1–IPROPI4), each sourcing 212 µA per ampere of high-side MOSFET current. Connecting an external resistor (e.g., 3.09 kΩ for 5A full-scale) converts this to a voltage (VIPROPI) readable by an MCU ADC. Accuracy is ±3.5% from 40–100% of rated current. External shunt resistors may be added between PGND and system ground if higher precision is required.
Can DRV8962QDDWRQ1 drive a stepper motor?
Yes, DRV8962QDDWRQ1 can drive a bipolar stepper motor by configuring two half-bridges (e.g., OUT1/OUT2 and OUT3/OUT4) as one complete H-bridge per phase. Its independent ENx/INx control, 5A per channel rating, and integrated current sensing allow microstepping with torque feedback. The device supports both slow-decay (INx PWM) and fast-decay (ENx PWM) modes for optimal current regulation during stepping sequences.
What protection features are integrated into DRV8962QDDWRQ1?
DRV8962QDDWRQ1 includes VM undervoltage lockout (4.23 V rising), charge pump undervoltage detection, overcurrent protection (8 A peak), and thermal shutdown (150°C). Fault conditions are reported via open-drain nFAULT pin. Recovery behavior (latch-off or auto-retry) is selected by the OCPM pin voltage. All protections operate across the full –40°C to +125°C ambient range and are AEC-Q100 qualified.
Is DRV8962QDDWRQ1 compatible with 1.8V logic inputs?
Yes, DRV8962QDDWRQ1 supports 1.8V, 3.3V, and 5.0V logic inputs on all control pins (IN1–IN4, EN1–EN4, MODE, OCPM, nSLEEP). Input logic-high threshold is 1.5V minimum, and hysteresis is 100 mV (300 mV on nSLEEP), ensuring noise immunity. No level-shifting circuitry is required when interfacing with modern low-voltage MCUs used in automotive domain controllers.
