Product details
Overview
DRV3204EPHPQ1 from Texas Instruments is an AEC-Q100 Grade 0 qualified three-phase N-channel MOSFET pre-driver IC for automotive BLDC motor control, featuring integrated charge pump (no bootstrap required), 3 high-side + 3 low-side pre-drivers, SPI interface, motor current sensing with ±5 mV offset, and fault diagnostics including overcurrent (119.7–146.3 A threshold), overtemperature (155–195 °C shutdown), and VB undervoltage/overvoltage monitoring - used in oil, fuel, and water pump systems.
For engineers reviewing the DRV3204EPHPQ1 datasheet, DRV3204EPHPQ1 pinout, DRV3204EPHPQ1 application, or DRV3204EPHPQ1 equivalent, key selection considerations include its 48-pin HTQFP package, 5.3–26.5 V VB operating range, 20 kHz PWM capability, integrated 5-V and 3.3-V regulators, and diagnostic flag reporting via FAULT pin and SPI register flags.
Technical Context
The DRV3204EPHPQ1 implements a fully configurable three-phase gate drive architecture using parallel input (CTLxH/CTLxL) or SPI-controlled commutation logic, with independent high-side (UH/VH/WH) and low-side (UL/VL/WL) outputs referenced to PDCPV and NGND respectively. Its charge-pump block generates up to VB + 14 V (at VB = 18 V, 0 mA load) to sustain high-side FET gate drive without external bootstrap circuitry.
Motor phase sensing uses differential inputs (PH1M/PH2M/PH3M, PHTM) with programmable hysteresis (0–200 mV), while current sensing employs a battery-common-mode amplifier (ALP/ALM/ALFB) with externally set gain (10–30 V/V) and 1 mΩ shunt compatibility. Fault detection includes latchable or non-latchable modes via SPI-configurable FLTCFG register bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating VB Range | 5.3 V to 26.5 V - supports 12 V and 24 V automotive battery systems with robust undervoltage lockout (VBUVTH = 4.35–5.85 V) and overvoltage protection (VBOV = 26.5–28.5 V) |
| PWM Frequency Support | Up to 20 kHz - enables high-efficiency, low-audible-noise motor control in oil/fuel/water pumps |
| Charge Pump Output | PDCPV = VB + 10 V to VB + 14 V (typ.) - eliminates need for bootstrap capacitors and enables reliable high-side N-FET drive |
| Motor Current Sense Accuracy | ±5 mV input offset, 29.4–30.6 mV/A linearity, 1–2.5 µs settling time - enables precise real-time current feedback for closed-loop torque control |
| Fault Detection Thresholds | Overcurrent: 119.7–146.3 A (Rshunt = 1 mΩ); Thermal shutdown: 155–195 °C; VCC UV: 3.7–4.5 V - provides layered safety for ASIL-B-relevant applications |
| SPI Interface | 4 MHz max clock, 16-bit frame, slave mode - allows full configuration of dead time (0.5–2.2 µs), fault latching, and diagnostic readback |
| Regulators | 5.0 V ±0.1 V @ 150 mA (VCC), 3.3 V ±0.3 V @ 100 mA (VDD) - powers MCU and peripherals without external LDOs |
Pinout & Package
Package: 48-pin HTQFP (7.00 mm × 7.00 mm), RoHS-compliant, thermally enhanced with exposed thermal pad (θJA = 26.1 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase pre-driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3205AQPHPRQ1 | Pin-compatible upgrade with higher charge-pump current (22 mA vs 18 mA), extended VB range (4.5–28 V), and improved thermal resistance (θJA = 23.5 °C/W) | Supports higher-power pumps (>1 kW) and wider battery voltage transients; retains identical SPI register map and fault reporting | Preferred for new designs requiring longer automotive lifecycle support and higher drive capability |
| MP6532DS-LF-Z | Monolithic 3-phase driver (integrated FETs), no external MOSFETs required; lower voltage rating (VB = 6–28 V), no integrated current sense amplifier | Targets lower-power (<300 W) applications; eliminates gate-drive loop layout but forfeits design flexibility and high-current sensing precision | Consider only when board space is severely constrained and peak motor current <15 A |
Compared with DRV3204EPHPQ1, the DRV3205AQPHPRQ1 offers higher reliability margin in thermal and electrical stress conditions while maintaining full software compatibility, whereas MP6532DS-LF-Z trades configurability and sensing fidelity for integration density - making DRV3204EPHPQ1 optimal for mid-power, diagnostics-critical automotive pumps.

The DRV3204EPHPQ1 supports PWM frequencies up to 20 kHz, enabling high-efficiency, low-audible-noise operation in automotive BLDC motor applications such as oil and water pumps. This limit is determined by internal pre-driver propagation delays (ton_h/toff_h ≤ 200 ns) and charge-pump regulation stability under dynamic load.
Does the DRV3204EPHPQ1 require external bootstrap capacitors for high-side drive?
No, the DRV3204EPHPQ1 integrates a charge-pump circuit that generates PDCPV (up to VB + 14 V) to drive high-side N-FET gates, eliminating the need for external bootstrap diodes and capacitors. This architecture supports 100% duty-cycle operation and improves reliability in high-vibration automotive environments.
How does the DRV3204EPHPQ1 implement motor current sensing?
The DRV3204EPHPQ1 uses a dedicated battery-common-mode current-sense amplifier with inputs ALP (positive), ALM (negative), and ALFB (feedback). Gain is set externally (10–30 V/V), and output ALV provides a 0.5–2.5 V signal proportional to motor current with ±5 mV offset and 29.4–30.6 mV/A linearity - compatible with 1 mΩ shunts.
What fault conditions trigger the FAULT pin on the DRV3204EPHPQ1?
The FAULT pin on the DRV3204EPHPQ1 asserts low for overcurrent (MTOC), overtemperature (TSD), VCC undervoltage/overvoltage, VB undervoltage/overvoltage, and power-bridge faults. Behavior is configurable via SPI (FLTCFG register) as either latched or pulsed, and individual fault sources can be masked.
Is the DRV3204EPHPQ1 pin-compatible with any newer TI pre-driver ICs?
Yes, the DRV3204EPHPQ1 is pin-compatible with the DRV3205AQPHPRQ1, which offers enhanced specifications including higher charge-pump current (22 mA), improved thermal performance (θJA = 23.5 °C/W), and extended VB range (4.5–28 V), while retaining identical pinout, SPI register mapping, and functional behavior.
