Product details
Overview
DRV83055QPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive three-phase smart gate driver IC for BLDC/PMSM motor control, featuring integrated 5-V/50-mA LDO, three bidirectional current-shunt amplifiers (gain programmable 10–78.8 V/V), 4.4–45 V operation, and SPI-configurable gate drive (1.25-A peak sink, 1-A peak source). It enables high-reliability fuel pump and HVAC blower drives in engine compartments.
For engineers reviewing the DRV83055QPHPRQ1 datasheet, DRV83055QPHPRQ1 pinout, DRV83055QPHPRQ1 application, or DRV83055QPHPRQ1 equivalent, this page delivers verified technical context, exact pin functions, real-world automotive use cases, and validated alternative options - all grounded in TI's SLVSD12D production datasheet and official device specifications.
Technical Context
The DRV83055QPHPRQ1 implements a smart gate drive architecture with independent IDRIVE/TDRIVE programming for high- and low-side MOSFETs, programmable slew-rate control, and automatic handshaking to prevent shoot-through. Its charge-pump-based high-side driver supports 100% duty cycle and cold-crank operation down to 4.4 V.
It integrates three precision current-shunt amplifiers with adjustable gain (10/19.9/39.8/78.8 V/V), ±4 mV input offset, and 300–2400 ns settling time depending on gain setting, plus a dedicated 5-V/50-mA LDO with ±3% line/load regulation - all monitored and configured via SPI with fault reporting and watchdog support.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV83053QPHPRQ1 | Same 48-pin HTQFP package and feature set, but includes 3.3-V/50-mA LDO instead of 5-V LDO. | Used where MCU or peripheral logic operates at 3.3 V and requires tighter voltage matching. | Select when system power architecture mandates 3.3-V bias rail; pinout and SPI register map are identical. |
| DRV8323RSRTVRQ1 | 40-pin WQFN package; includes dual 10-bit ADCs and enhanced SPI diagnostics; no integrated LDO. | Targets space-constrained EPS or steering column modules needing higher-resolution current sampling and compact layout. | Choose when board area is limited and external 3.3-V/5-V regulators are already present; requires additional power design effort. |
Compared with DRV83055QPHPRQ1, DRV83053QPHPRQ1 offers identical functionality with only LDO voltage difference - making it a direct drop-in replacement if 3.3-V supply suffices; DRV8323RSRTVRQ1 trades LDO integration for smaller footprint and ADC capability, demanding revised power and signal routing.

FAQ
What is the LDO output voltage and current capability of the DRV83055QPHPRQ1?
The DRV83055QPHPRQ1 integrates a fixed 5-V LDO rated for up to 50 mA output current. It features ±3% DC regulation over line and load, with 20 mV line regulation (5.3–12 V input) and 50–150 mV load regulation (100 µA–50 mA). The VREG pin requires a 1-µF ceramic capacitor to GND for stability, and the LDO remains active only when EN_GATE is asserted high.
Does the DRV83055QPHPRQ1 support both 3-PWM and 6-PWM input modes?
Yes, the DRV83055QPHPRQ1 supports both 3-PWM (INHA/INHB/INHC only) and 6-PWM (INHA–INLC) control schemes via hardware pin configuration and SPI register settings. The device automatically detects mode based on INLx pin states at power-up, and allows dynamic switching between modes through SPI command - enabling flexible MCU interface options for trapezoidal or FOC commutation.
How does the DRV83055QPHPRQ1 protect against MOSFET shoot-through?
The DRV83055QPHPRQ1 prevents shoot-through using hardware-based automatic handshaking between high- and low-side gate drivers, enforced by internal logic that guarantees minimum dead time (280 ns base + programmable 35–5280 ns). It also monitors VDS of both MOSFETs in real time and disables affected half-bridges within 1 µs of overvoltage detection - eliminating reliance on MCU timing margins.
What are the key differences between DRV83055QPHPRQ1 and DRV83053QPHPRQ1?
The DRV83055QPHPRQ1 and DRV83053QPHPRQ1 share identical pinout, package, SPI register map, gate drive specs, and temperature rating (Grade 1, –40°C to +125°C); their sole difference is LDO output voltage - 5 V for DRV83055QPHPRQ1 versus 3.3 V for DRV83053QPHPRQ1. All other electrical characteristics, protection features, and current-sense amplifier performance are functionally identical.
Can the current-shunt amplifiers in the DRV83055QPHPRQ1 be used for bidirectional motor current measurement?
Yes, the three integrated current-shunt amplifiers in the DRV83055QPHPRQ1 support true bidirectional measurement via differential inputs (SPx/SNx) with ±0.48 V differential input range and programmable gain (10–78.8 V/V). Their ±4 mV input offset and <3.5% gain error ensure accurate zero-crossing detection and torque estimation in both motoring and regenerative braking phases of BLDC/PMSM operation.
