DRV8340HPHPRQ1

Overview

The DRV8340HPHPRQ1 is an automotive-grade, three-phase smart gate driver designed for brushless DC (BLDC) motor applications. It integrates a hardware-based commutation controller with three half-bridge drivers capable of sourcing and sinking up to 25 mA per output. The device operates within a supply voltage range of 5.5 V to 60 V and supports PWM frequencies up to 200 kHz. It is housed in a 48-pin HTQFP package and is qualified to AEC-Q100 standards for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates hardware-based commutation logic for simplified control interface
• Provides three high-side and three low-side half-bridge outputs
• Supports direct connection to Hall effect sensors for rotor position feedback

Applications

• Automotive cooling fan motors
• Electric power steering systems
• Water pump controllers in vehicle thermal management

Procurement Notes
