DRV8873HPWPRQ1

Overview

The DRV8873HPWPRQ1 is an automotive-grade half-bridge motor driver IC designed for brushed DC motors. It features a 24-PowerTSSOP package and supports a supply voltage range of 4.5V to 38V. The device delivers a peak output current of 10A with low on-resistance (150mΩ at 25°C). It operates within a temperature range of -40°C to 125°C and holds AEC-Q100 qualification. Key electrical parameters include a 10µA low-power sleep mode current and compatibility with 1.8V, 3.3V, or 5V logic inputs.

Feature Summary

• Integrates four N-channel MOSFETs in a half-bridge configuration for bidirectional motor control.
• Provides current mirror functionality for load current monitoring without high-power resistors.
• Supports configurable control interfaces including PH/EN, PWM, and independent half-bridge modes.
• Includes comprehensive protection mechanisms such as overcurrent, short circuit, and thermal shutdown.

Applications

• Electronic throttle control systems
• Exhaust gas recirculation actuators
• Side mirror tilt adjustment mechanisms
• Electronic shifter applications

Procurement Notes

Verify the specific suffix 'H' against the official datasheet to confirm pinout and functional equivalence, as ordering suffixes may indicate variations in packaging or testing criteria. Ensure the component meets AEC-Q100 Grade 1 requirements for the intended automotive environment. Cross-reference the 24-PowerTSSOP footprint dimensions with the target PCB layout to guarantee mechanical fit and thermal performance.

Selection Notes

Select this component for applications requiring a single half-bridge capable of driving brushed DC motors up to 10A peak current. It is suitable for designs needing integrated current sensing via a current mirror rather than external shunt resistors. Consider the 4.5V to 38V input range for compatibility with standard automotive power rails. Evaluate the need for SPI versus hardware interface options based on system complexity.

Part Context

This part belongs to the DRV8873 family of half-bridge motor drivers from Texas Instruments. It is specifically qualified for automotive use under the AEC-Q100 standard. The device serves as a compact solution for controlling electromagnetic loads, offering integration of both control logic and power stages in a small surface-mount package.
