DRV8343HPHPRQ1

Overview

The DRV8343HPHPRQ1 is an automotive-grade, three-phase brushless DC motor controller and driver manufactured by Texas Instruments. It integrates a high-voltage gate driver with a dedicated BLDC controller in a single package. The device supports a supply voltage range of 5.5 V to 60 V and operates within a temperature range of -40°C to +125°C. It features six output channels for driving external power MOSFETs and includes hardware-based commutation logic. The component is AEC-Q100 qualified and housed in a 48-pin HTQFP package.

Feature Summary

• Integrates a three-phase smart gate driver with a dedicated BLDC controller for simplified system design
• Supports hardware-based commutation using Hall effect sensor inputs for robust motor control
• Includes integrated bootstrap diodes and charge pump circuitry for efficient high-side gate drive
• Features comprehensive protection mechanisms including overcurrent, overvoltage, undervoltage, and thermal shutdown

Applications

• Automotive cooling fan motors
• Electric power steering systems
• Water pump controllers
• Blower motor applications

Procurement Notes

Verify the specific suffix HPHPRQ1 against the official Texas Instruments datasheet to confirm pinout and functional compatibility. Ensure that the ordering information matches the required automotive qualification standards. Cross-reference the package dimensions with the mechanical outline drawing prior to PCB layout finalization.

Selection Notes

Select this component when a combined controller and driver solution is required for three-phase BLDC motors in automotive environments. It is suitable for designs needing hardware commutation to reduce microcontroller load. Consider the 60 V rating and integrated protection features for high-reliability applications where external discrete components should be minimized.

Part Context

This part belongs to the DRV8343-Q1 family of automotive motor drivers. It is distinct from the DRV8340 series, which typically utilizes different interface protocols such as PWM or SPI rather than the hardware-based commutation focus of the DRV8343. The Q1 designation indicates compliance with automotive reliability standards.
