Product details
Overview
DRV3245AQPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 (−40°C to +125°C) three-phase automotive gate driver IC for N-channel MOSFETs, featuring programmable 1-A peak gate drive current, integrated 3× current-shunt amplifiers, real-time phase comparators, and SPI-configurable protection. It enables high-reliability motor control in electrical power steering and brake assist systems.
For engineers reviewing the DRV3245AQPHPRQ1 datasheet, DRV3245AQPHPRQ1 pinout, DRV3245AQPHPRQ1 application, or DRV3245AQPHPRQ1 equivalent, key selection criteria include ASIL D functional safety compliance, 4.5–45-V operating range, 100% duty-cycle charge-pump operation, thermally enhanced HTQFP-48 packaging, and integrated diagnostics for ISO 26262 system design.
Technical Context
The DRV3245AQPHPRQ1 implements a three-half-bridge gate driver architecture with independent high-side and low-side drivers per phase, supported by an internal charge-pump enabling 100% duty cycle operation during cold-crank conditions. Its integrated current-shunt amplifiers provide low-drift offset sensing, while phase comparators deliver real-time status via SPI.
Functional safety is embedded at the silicon level: systematic capability up to ASIL D is achieved through clock monitoring, SPI CRC, analog BIST, programmable dead-time control, MOSFET VDS overcurrent detection, and gate-source voltage real-time monitoring - all reportable via SPI interface.

FAQ
What is the maximum PWM frequency supported by the DRV3245AQPHPRQ1?
The DRV3245AQPHPRQ1 supports PWM input frequencies up to 20 kHz in both 3-PWM and 6-PWM modes. This enables high-resolution motor control for applications such as electric power steering where fast torque response is essential. The device maintains timing integrity and gate drive strength across the full 4.5–45-V operating range, and DRV3245AQPHPRQ1's internal propagation delay remains stable under thermal stress.
Does the DRV3245AQPHPRQ1 support 100% duty cycle operation?
Yes, the DRV3245AQPHPRQ1 integrates a charge-pump gate driver that enables true 100% high-side duty cycle operation - critical for maintaining motor torque during low-battery cold-crank conditions down to 4.5 V. This capability is verified across the full −40°C to +125°C temperature range and is intrinsic to the DRV3245AQPHPRQ1 silicon design.
How many current-shunt amplifiers does the DRV3245AQPHPRQ1 integrate?
The DRV3245AQPHPRQ1 integrates three current-shunt amplifiers (CSA, CSB, CSC), each with matched gain and offset characteristics over temperature. These amplifiers directly interface with external shunt resistors and feed phase current data to internal comparators and SPI-accessible registers - a key differentiator from the 2-amplifier B variant and standard-precision version of the DRV3245AQPHPRQ1.
What functional safety documentation is available for the DRV3245AQPHPRQ1?
Texas Instruments provides ISO 26262 documentation for the DRV3245AQPHPRQ1, including FMEDA reports, safety manuals, and diagnostic coverage analysis supporting ASIL D system integration. All documentation is accessible via TI's functional safety portal and applies specifically to the DRV3245AQPHPRQ1 device marking and qualification scope.
Is the DRV3245AQPHPRQ1 pin-compatible with other variants in the DRV3245Q-Q1 family?
Yes, all DRV3245Q-Q1 variants - including DRV3245AQPHPRQ1, DRV3245BQPHPRQ1, DRV3245CQPHPRQ1, and DRV3245SQPHPRQ1 - share identical HTQFP-48 (PHP) packaging, pinout, and mechanical footprint. This enables hardware reuse across safety and precision variants, with differentiation handled entirely via firmware configuration and internal analog block enablement.
