Product details
Overview
DRV3201QPAPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified 3-phase BLDC gate driver IC for automotive safety-critical motor control. It drives six N-channel MOSFETs (up to 250-nC gate charge), features programmable 140-mA to 1-A gate current, integrated boost converter, dual-stage current sense amplifiers, and SPI-based diagnostics - deployed in electric power steering and brake assist systems.
For engineers reviewing the DRV3201QPAPRQ1 datasheet, DRV3201QPAPRQ1 pinout, DRV3201QPAPRQ1 application, or DRV3201QPAPRQ1 equivalent, key selection considerations include gate drive compliance (–7 V to 40 V), 30-kHz PWM support, shoot-through protection with programmable dead time, phase comparators, and functional safety monitoring via SPI.
Technical Context
The DRV3201QPAPRQ1 integrates three half-bridge drivers with independent high-side/low-side control inputs (GHSx/SHSx/SLSx/GLSx), each supporting 140-mA to 1-A programmable sink/source current and –7 V to 40 V pin tolerance. Its internal boost converter enables full gate drive down to 4.75-V battery input, while three real-time phase comparators monitor commutation timing.
Two integrated current sense amplifiers provide first-stage gain plus two programmable second-stage gains for high-resolution low-current sensing; fault reporting (short circuit, overtemperature, OV/UV) and safety state management are handled through a dedicated SPI interface with configurable warning/shutdown thresholds.

FAQ
What is the maximum gate charge DRV3201QPAPRQ1 can drive per MOSFET?
The DRV3201QPAPRQ1 supports up to 250 nC total gate charge per power MOSFET. This rating is validated across its full operating voltage range (4.75 V to 30 V) and gate drive current range (140 mA to 1 A), ensuring reliable turn-on/turn-off of high-side and low-side N-channel devices used in automotive 3-phase inverters. The DRV3201QPAPRQ1 achieves this with integrated boost conversion and robust pin voltage tolerance.
Does DRV3201QPAPRQ1 support sensorless BLDC commutation?
Yes, the DRV3201QPAPRQ1 includes three real-time phase comparators that monitor back-EMF zero-crossing events directly on motor terminals. These comparators operate independently of the SPI interface and enable hardware-accelerated sensorless commutation - eliminating the need for external comparators or high-speed ADC sampling in EPS and oil pump applications. The DRV3201QPAPRQ1 uses these signals internally to synchronize gate timing.
How does the integrated boost converter in DRV3201QPAPRQ1 function?
The DRV3201QPAPRQ1 integrates a boost converter with internal switch FET, controlled via VS, SW, and BOOST pins. When paired with an external inductor and capacitor, it generates a regulated >10-V supply for gate driving - maintaining full MOSFET enhancement even during 4.75-V battery cold-crank events. This eliminates dependency on external high-voltage rails and simplifies power architecture in 12-V automotive systems. The DRV3201QPAPRQ1 monitors boost health via SPI registers.
What current sensing architecture does DRV3201QPAPRQ1 use?
The DRV3201QPAPRQ1 integrates two differential current sense amplifiers with fixed first-stage gain and two programmable second-stage gains (selectable via SPI). Each amplifier accepts inputs from dedicated shunt resistors (IN1/IP1 and IN2/IP2) and delivers amplified, offset-compensated outputs for MCU ADC capture. This dual-stage approach provides high resolution at both low and high current levels - critical for torque accuracy in EPS and brake assist. The DRV3201QPAPRQ1 supports simultaneous sampling of both phases.
Is DRV3201QPAPRQ1 pin-compatible with other TI 3-phase drivers?
The DRV3201QPAPRQ1 shares the same 64-pin HTQFP (PAP) package and pinout with the DRV3205QPAPRQ1, enabling drop-in replacement where higher gate drive current (1.5 A) or added watchdog functionality is not required. However, it is not pin-compatible with earlier-generation drivers like the DRV8301 or non-Q1 variants due to differences in SPI mapping, current sense routing, and safety feature allocation. Always verify layout compatibility using the DRV3201QPAPRQ1-specific package drawing.
