Texas Instruments DRV3204EPHPRQ1

Overview

DRV3204EPHPRQ1 from Texas Instruments is an AEC-Q100 Grade 0 qualified three-phase BLDC motor pre-driver IC for automotive oil, fuel, and water pumps. It integrates three high-side and three low-side N-channel MOSFET pre-drivers, a charge pump (no bootstrap required), SPI interface, motor current sense amplifier (±100 A range), 5-V regulator, and MCU reset generator. Operates from 5.3 V to 26.5 V VB supply.

For engineers reviewing the DRV3204EPHPRQ1 datasheet, DRV3204EPHPRQ1 pinout, DRV3204EPHPRQ1 application, or DRV3204EPHPRQ1 equivalent, key selection criteria include integrated high-side gate drive without bootstrap capacitors, battery-common-mode current sensing up to 100 A, programmable dead time (0.5–2.2 µs), thermal shutdown at 155–195 °C, and fault diagnostics including overcurrent, overvoltage, undervoltage, and overtemperature.

Technical Context

The DRV3204EPHPRQ1 implements a fully configurable three-phase pre-driver architecture with independent high-side (PDCPV-referenced) and low-side (NGND-referenced) outputs. Its charge pump generates up to VB + 14 V (at VB = 18 V, 0 mA load) to sustain high-side gate drive, eliminating external bootstrap networks. Phase comparators accept motor back-EMF inputs (PH1M–PH3M, PHTM) for sensorless commutation feedback.

Motor current sensing uses a differential amplifier (ALP/ALM/ALFB) with externally set gain (10–30 V/V) and programmable overcurrent threshold (119.7–146.3 A). All pre-driver timing-turn-on/off delays (≤200 ns), dead time (configurable via SPI register PDCFG.DEADT), and propagation delays-is digitally controlled and verified across –40°C to 150°C ambient.

FAQ

What is the maximum motor phase current supported by the DRV3204EPHPRQ1 current sense circuit?

The DRV3204EPHPRQ1 current sense amplifier supports motor phase currents up to 100 A when configured with a 1 mΩ shunt resistor, 30 V/V gain, and 2.5 V ADTH reference voltage. The overcurrent detection threshold is programmable from 119.7 A to 146.3 A, and settling time remains ≤2.5 µs for ±1% accuracy during fast current transients. This capability is validated across the full –40°C to 150°C operating range.

Does the DRV3204EPHPRQ1 require external bootstrap capacitors for high-side gate drive?

No, the DRV3204EPHPRQ1 does not require external bootstrap capacitors. It integrates a charge pump that generates PDCPV up to VB + 14 V, providing sufficient gate drive voltage for high-side N-channel MOSFETs without bootstrap diodes or capacitors. This simplifies PCB layout, improves reliability in high-vibration environments, and eliminates bootstrap-related timing constraints during PWM operation.

How is the dead time between high-side and low-side pre-driver outputs configured on the DRV3204EPHPRQ1?

Dead time on the DRV3204EPHPRQ1 is configured exclusively via the SPI interface using the PDCFG register's DEADT bits (bits 1:0). Four selectable values are available: 2.2 µs, 1.7 µs, 1.2 µs, and 0.7 µs - each with ±0.1 µs tolerance. This digital configuration avoids external RC networks, ensures consistent timing across temperature, and allows runtime adjustment during motor commutation sequences.

What fault conditions trigger the FAULT pin assertion on the DRV3204EPHPRQ1?

The FAULT pin on the DRV3204EPHPRQ1 asserts low for five confirmed fault conditions: motor overcurrent (MTOC), junction overtemperature (>155°C), VB overvoltage (>28.5 V), VB undervoltage (<4.35 V), and VCC undervoltage (<3.7 V). Each fault is independently maskable via SPI registers, and FAULT behavior (latched vs. auto-clear) is configurable through FLTCFG register settings. The pin is open-drain and requires external pull-up.

Is the DRV3204EPHPRQ1 pin-compatible with any newer Texas Instruments pre-driver ICs?

Yes, the DRV3204EPHPRQ1 is pin-compatible with the DRV3205AQPHPRQ1, its direct successor. Both share identical 48-pin HTQFP packaging, pin functions, and mechanical footprint. The DRV3205AQPHPRQ1 adds enhanced HBM/CDM ESD ratings (H3/C3), extended VB range (4.5–28 V), and improved charge pump efficiency, but retains full electrical and software compatibility with existing DRV3204EPHPRQ1 designs.
