DRV8432DKDR

Full Half-Bridge (H Bridge) Drivers Overview

The DRV8432DKDR is a dual full-bridge PWM motor driver manufactured by Texas Instruments, designed for driving brushed DC or single bipolar stepper motors. It integrates four half-bridge drivers within a 36-pin HSSOP package with exposed pad. The device supports a supply voltage range of 10.8V to 13.2V and can handle load voltages up to 52.5V. It delivers a continuous output current of 7A per channel with peak currents reaching 12A to 15A depending on thermal conditions. The integrated power MOSFETs feature typical on-resistances of 110 milliohms for both high-side and low-side switches.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify component authenticity through authorized channels due to obsolescence status. Confirm package integrity and pin alignment against the 36-HSSOP specification. Check datasheet revisions for any manufacturing site changes noted in product change notices. Ensure compatibility with existing PCB footprints and thermal design requirements before integration.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for applications requiring dual-channel motor drive capability with integrated power switching. Consider the thermal performance constraints associated with the HSSOP-36 package when designing heat dissipation solutions. Evaluate the 52.5V maximum load voltage limit against system requirements. Verify that the 7A continuous current rating meets the specific motor load demands.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the DRV84xx family of motor drivers from Texas Instruments, which are optimized for low-cost, high-performance motor control applications. The DRV8432 specifically targets dual brushed DC or single stepper motor use cases. It replaces older discrete solutions by integrating gate drivers and power stages into a single compact package, reducing board space and component count.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

The DRV8432DKDR has been officially observed/obsolete. No direct functional substitute part numbers are confirmed in the provided documentation. Designers should evaluate alternative motor driver ICs from Texas Instruments or other manufacturers that offer similar current ratings and package configurations.
