DRV8904QPWPRQ1

Full Half-Bridge (H Bridge) Drivers Overview

The DRV8904QPWPRQ1 is an automotive-grade, four-channel half-bridge motor driver designed for high-current applications. It supports a supply voltage up to 40 V and delivers continuous output currents of 6 A per channel with peak capabilities exceeding these limits. The device integrates charge pump circuitry for high-side gate drive and includes comprehensive protection features such as overcurrent, overtemperature, undervoltage lockout, and cross-conduction prevention. Packaged in a thermally enhanced PWPR QFN format, it ensures reliable operation within the specified automotive temperature range.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel quantity and packaging style. Confirm that the component meets the necessary AEC-Q100 reliability standards for your target automotive application segment. Ensure compatibility with the host controller logic levels and check for any recent product change notifications regarding pinout or electrical characteristics before finalizing the design.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this driver when multiple independent motor channels are required within a single package to reduce board space. Consider its 6 A continuous current rating for medium-power actuator loads. Evaluate the thermal performance requirements based on the expected duty cycle and ambient temperature conditions. Compare against single-channel drivers if only one or two actuators need control to optimize cost and complexity.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to Texas Instruments' DRV89xx family of automotive motor drivers. It complements other solutions like the DRV8912 by offering a balanced combination of channel count and current capacity. The series is designed to simplify system architecture by integrating control logic and power stages into a compact form factor suitable for modern vehicle electronics.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

Direct substitutes include other TI automotive half-bridge drivers with similar channel counts and current ratings, such as the DRV8932QPWPRQ1. Verify pin-to-pin compatibility and electrical parameter alignment before swapping. Non-TI equivalents require careful evaluation of interface timing and protection feature parity.
