Product details
Overview
DRV3203EPHPQ1 from Texas Instruments is a three-phase BLDC motor pre-driver IC for automotive applications, integrating six N-channel MOSFET pre-drivers (three high-side, three low-side), a charge pump (no bootstrap capacitor required), SPI interface, motor current sensing with programmable gain, and comprehensive fault diagnostics including overcurrent, overvoltage, undervoltage, overtemperature, and power-bridge faults. It operates from 5.3 V to 26.5 V VB supply and supports PWM up to 20 kHz in oil, fuel, and water pump control systems.
For engineers reviewing the DRV3203EPHPQ1 datasheet, DRV3203EPHPQ1 pinout, DRV3203EPHPQ1 application, or DRV3203EPHPQ1 equivalent, key selection considerations include its AEC-Q100 Grade 0 qualification (–40°C to +150°C ambient), integrated 3.3-V regulator, MCU reset generator, phase comparator inputs for sensorless commutation, and high-side gate drive capability via charge-pump outputs (PDCPV, CPDR1–CPDR4).
Technical Context
The DRV3203EPHPQ1 implements a parallel-input pre-driver architecture controlled by an external MCU, where CTLxH/CTLxL signals directly configure high-side and low-side output states. Its charge-pump circuit generates regulated high-side gate drive voltage (e.g., VB + 12 V at 12 V input) without requiring external bootstrap components, enabling robust operation across the full 5.3–26.5 V VB range.
Diagnostics are implemented via dedicated analog comparators and digital registers: motor overcurrent detection uses ALP/ALM/ALFB inputs with programmable threshold (OVADth = 99 A typical, Rshunt = 1 mΩ), while thermal shutdown triggers at 175°C with 10°C hysteresis. Phase comparison (PH1M/PH2M/PH3M/PHTM) supports sensorless BLDC commutation, and SPI (4 MHz max, 16-bit frame) enables real-time register read/write for configuration and fault status.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VB) | 5.3 V to 26.5 V - supports full automotive battery range including cold-crank and load-dump conditions. |
| PWM Frequency | Up to 20 kHz - enables high-efficiency motor control with minimal audible noise in pump applications. |
| Charge-Pump Output (PDCPV) | VB + 12 V typical at 12 V input - eliminates need for bootstrap capacitors and simplifies high-side gate drive design. |
| Motor Current Sense Gain | 10–30 V/V programmable - allows precise 0–60 A measurement using 1 mΩ shunt resistor and external gain-setting resistors. |
| SPI Interface | 4 MHz max clock, 16-bit frame, slave mode - provides deterministic, low-latency register access for real-time diagnostics and configuration. |
| AEC-Q100 Grade | Grade 0 (–40°C to +150°C ambient) - qualified for under-hood automotive motor control environments. |
| Thermal Shutdown | 175°C trip point with 10°C hysteresis - protects device and external FETs during sustained overload or cooling failure. |
Pinout & Package
DRV3203EPHPQ1 is housed in a 48-pin HTQFP (PHP) package with 7.00 mm × 7.00 mm body size and exposed thermal pad for enhanced heat dissipation in automotive motor-control modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| UH, VH, WH | High-side pre-driver outputs | Drive gates of external N-channel high-side FETs; referenced to PDCPV for full enhancement. |
| UL, VL, WL | Low-side pre-driver outputs | Drive gates of external N-channel low-side FETs; referenced to NGND for standard logic-level drive. |
| PDCPV, CPDR1–CPDR4 | Charge-pump outputs | Provide regulated high-voltage supply (e.g., VB + 12 V) for high-side gate drive; eliminate bootstrap capacitor requirement. |
| ALP, ALM, ALFB, AREF, ALV | Motor current-sense interface | Support differential shunt sensing with programmable gain; ALV delivers amplified motor current signal (0.5–1.5 V) to MCU ADC. |
| PH1M, PH2M, PH3M, PHTM | Phase comparator inputs | Enable sensorless commutation by comparing back-EMF zero-crossings against reference PHTM; support trapezoidal control. |
| CS, DIN, DOUT, SCK | SPI interface signals | Enable full register read/write access for configuration, diagnostics, and fault flag clearing; 4 MHz max clock ensures fast updates. |
| ENABLE, RES, PRN, FAULT | System control & diagnostics | ENABLE activates pre-drivers; RES resets external MCU; PRN feeds watchdog timer; FAULT asserts low on any critical fault event. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Generates stable high-side gate voltage (VB + 12 V) without external bootstrap components, reducing BOM count and layout complexity. |
| Programmable motor current sense | Configurable gain (10–30 V/V) and offset via SPI registers enables accurate 0–60 A measurement with 1 mΩ shunt and standard MCU ADC. |
| Comprehensive fault diagnostics | Detects and reports overcurrent (OVADth = 99 A), VB over/undervoltage, VCC/VDD faults, thermal shutdown (175°C), and power-bridge failures via FAULT pin and SPI flags. |
| MCU watchdog & reset generator | Monitors PRN pulse pattern and VCC level; asserts RES signal to reset external MCU if watchdog timeout or VCCUV occurs (2.2 V threshold). |
| Sensorless commutation support | Dedicated phase comparator inputs (PH1M/PH2M/PH3M/PHTM) with 1.3–4.5 V common-mode range enable reliable back-EMF zero-crossing detection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase BLDC pre-driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3205QPWPRQ1 | Higher VB range (4.5–45 V), integrated 5-V LDO, no charge pump (requires bootstrap), 40-pin TSSOP. | Better suited for 48-V mild-hybrid systems; lacks integrated charge pump and sensorless phase comparator inputs. | Select when higher input voltage tolerance is required and bootstrap design is acceptable; not drop-in due to pinout and feature differences. |
| MP6532GQ-Z | Monolithic 3-phase gate driver (integrated FETs), 5–28 V VB, no SPI, analog-only interface, 32-pin QFN. | Targeted at space-constrained cost-sensitive pumps; lacks programmable diagnostics, current sense, and sensorless commutation support. | Choose for simplified BOM and layout where MCU-level control granularity and advanced diagnostics are not required. |
Compared with DRV3203EPHPQ1, DRV3205QPWPRQ1 offers wider VB range but requires external bootstrap and omits phase comparators, while MP6532GQ-Z integrates power stages but sacrifices configurability and diagnostic depth-making DRV3203EPHPQ1 optimal for programmable, sensorless, AEC-Q100-compliant automotive pump control.

FAQ
What is the maximum PWM frequency supported by the DRV3203EPHPQ1?
The DRV3203EPHPQ1 supports PWM frequencies up to 20 kHz, enabling high-efficiency motor control with reduced audible noise-critical for automotive cabin comfort in oil, fuel, and water pump applications. This specification is confirmed in the official datasheet Section 1 Features and validated across the full –40°C to +150°C operating temperature range.
Does the DRV3203EPHPQ1 require an external bootstrap capacitor for high-side gate drive?
No, the DRV3203EPHPQ1 does not require an external bootstrap capacitor. Its integrated charge-pump circuit (with outputs PDCPV, CPDR1–CPDR4) generates a regulated high-side gate voltage (e.g., VB + 12 V at 12 V input), eliminating bootstrap dependency and improving reliability in high-vibration automotive environments.
How does the motor current sensing function work on the DRV3203EPHPQ1?
The DRV3203EPHPQ1 implements motor current sensing via differential inputs ALP/ALM with programmable gain (10–30 V/V) set by SPI registers. Using a 1 mΩ shunt resistor, it delivers a conditioned analog output (ALV) ranging from 0.5 V to 1.5 V corresponding to 0–60 A, referenced to AREF. Gain is adjusted via external resistors R11/R12/R21/R22 per datasheet Figure 5.
What fault conditions does the DRV3203EPHPQ1 monitor and report?
The DRV3203EPHPQ1 monitors and reports overcurrent (via OVADth = 99 A threshold), VB overvoltage (27.5 V) and undervoltage (4.15 V), VCC/VDD faults, thermal shutdown (175°C), and power-bridge faults. Fault status is indicated both by the active-low FAULT pin and individual flags accessible via SPI register reads, enabling layered diagnostic response.
Is the DRV3203EPHPQ1 pin-compatible with other members of the DRV320x-Q1 family?
No, the DRV3203EPHPQ1 is not pin-compatible with other DRV320x-Q1 variants such as DRV3205QPWPRQ1 (40-pin TSSOP) or DRV3201QPWPRQ1 (32-pin TSSOP). Its 48-pin HTQFP (PHP) package, pin functions (e.g., PDCPV, CPDR1–CPDR4, PHxM inputs), and internal architecture are unique to this part number and require dedicated PCB layout.
