For engineers reviewing the DRV8910QPWPRQ1 datasheet, DRV8910QPWPRQ1 pinout, DRV8910QPWPRQ1 application, or DRV8910QPWPRQ1 equivalent, this page delivers verified technical context, exact pin functions, real-world use cases, and validated alternative options for automotive motor control design.
Technical Context
The DRV8910QPWPRQ1 implements ten independent half-bridge output stages with matched high-side and low-side MOSFETs (RDS(ON) = 1.1 Ω typ at 25°C), programmable slew rate (0.6–2.5 V/µs), and configurable dead time (2–32 µs). Its 5-MHz SPI interface supports daisy-chaining and full register access for real-time fault reporting and PWM parameter updates.
It integrates four programmable 8-bit PWM generators, enabling individual channel current limiting and LED dimming control. Protection includes VM undervoltage lockout (UVLO), overvoltage protection (OVP), thermal warning/shutdown (OTW/OTSD), enhanced open-load detection (OLD), and per-channel overcurrent protection (OCP) with diagnostic readback via SPI.

Pinout & Package
DRV8910QPWPRQ1 uses a 24-pin HTSSOP package (7.80 mm × 4.40 mm) with exposed thermal pad for enhanced power dissipation. Pin numbering follows TI's standard top-view layout with GND pins at corners (1, 13, 24) and dual VM supply inputs (16, 21) for low-impedance motor rail connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1, 13, 24) | Power ground reference | Three dedicated ground pins reduce ground bounce and improve current return path integrity for all 10 channels. |
| OUT1–OUT10 | Half-bridge output terminals | Direct drive outputs for brushed DC motors/solenoids; OUT1–OUT10 map to physical pins 2, 23, 14, 11, 3, 10, 4, 22, 9, 15 respectively. |
| VM (16, 21) | Main motor supply input | Dual VM pins allow parallel routing to minimize IR drop and support >6-A combined continuous current delivery. |
| VDD (6) | Logic supply input | Accepts 3.0–5.5 V; requires local 0.1-μF ceramic + ≥1-μF bulk capacitor for stable SPI and register operation. |
| nSLEEP (8) | Driver enable control | Active-low input with internal pull-down; asserts sleep mode (<1.5 µA) when logic low, enabling rapid wake-up (200 µs). |
| nSCS (19) | SPI chip select | Active-low signal with internal pull-up; enables SPI communication only when asserted, supporting multi-device daisy chains. |
| SCLK (20), SDI (5), SDO (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. |
| nFAULT (12) | Open-drain fault indicator | Asserts logic low on any fault (OCP, OTSD, UVLO); requires external pull-up resistor to VDD or system rail. |
| NC (17, 18) | No-connect terminals | Unused pins - must be left floating or tied to GND per TI layout guidelines; no internal connection. |
Key Features
| Feature | Design Value |
|---|---|
| 10-channel half-bridge integration | Reduces BOM count and PCB area vs. discrete FET + gate driver solutions for multi-actuator automotive modules. |
| Configurable slew rate & dead time | Two slew rate modes (0.6/2.5 V/µs) and adjustable dead time (2–32 µs) suppress shoot-through and EMI in motor commutation. |
| Four programmable 8-bit PWM generators | Enables independent current limiting per channel or synchronized LED dimming without MCU timer resource consumption. |
| Enhanced open-load detection (OLD) | Detects open-circuit faults during active drive and passive (offline) states - critical for safety-critical HVAC and mirror position feedback. |
| AEC-Q100 Grade 1 qualification | Rated for –40°C to +125°C ambient operation with full production test screening - suitable for engine bay and cabin-mounted applications. |
