DRV8340SPHPRQ1

Overview

The DRV8340SPHPRQ1 is an automotive-grade, three-phase smart gate driver designed for brushless DC (BLDC) motor applications. It integrates a microcontroller unit with hard-wired interface control and three half-bridge drivers capable of handling supply voltages from 5.5 V to 60 V. The device operates within a temperature range of -40°C to +125°C and is housed in a 48-pin HTQFP package. It features a quiescent current of 12 mA and output drive currents of 25 mA, supporting frequencies up to 200 kHz.

Feature Summary

• Integrates MCU with hard-wired interface for simplified system design
• Supports 12-V to 24-V battery systems with 60-V load dump capability
• Includes integrated bootstrap diodes and charge pump for high-side driving

Applications

• Automotive cooling fans and blowers
• Electric power steering systems
• Water pumps in vehicle thermal management

Procurement Notes

Verify the specific suffix 'SPHP' confirms the 48-HTQFP package and lead-free RoHS compliance. Confirm AEC-Q100 qualification status matches project requirements. Check moisture sensitivity level (MSL 3) for proper storage and reflow soldering profiles. Ensure the hard-wired interface logic aligns with the host controller's pinout.

Selection Notes

Select this component when a hard-wired interface is preferred over SPI for cost-sensitive or simpler control architectures. It is suitable for applications requiring integrated bootstrap diodes and charge pumps without external discrete components. Compare against DRV8343 if digital communication interfaces are required instead of hard-wired signals.

Part Context

This part belongs to the DRV8340-Q1 family of three-phase smart gate drivers from Texas Instruments. It shares the same core hardware architecture as the DRV8340HPHPRQ1 but differs in the control interface configuration. The family targets automotive BLDC motor control applications requiring robust performance in harsh electrical environments.

Replacement Considerations

DRV8340HPHPRQ1 serves as a parameter-equivalent alternative within the same product family, differing primarily in interface configuration.
