DRV8705HQRHBRQ1 Description

Short technical summary and product information.

The DRV8705-Q1 from Texas Instruments is a highly integrated H-bridge smart gate driver designed for automotive applications. It supports a wide operating voltage range from 4.9V to 37V, with an absolute maximum rating of 40V. This device is AEC-Q100 qualified for Temperature Grade 1 (-40°C to +125°C TA).

 

Key features include a smart gate drive architecture with adjustable slew rate control, peak source and sink current outputs ranging from 0.5mA to 62mA, and integrated dead-time handshaking. It also incorporates a low-side current shunt amplifier with adjustable gain settings (10, 20, 40, 80V/V) and integrated feedback resistors. Multiple interface options are available, including SPI for detailed configuration and diagnostics, and Hardware (GPIO) for simplified control.

 

The DRV8705-Q1 is housed in a compact 32-VQFN package with wettable flanks. It offers robust protection features such as supply and regulator voltage monitors, MOSFET VDS overcurrent monitors, MOSFET VGS gate fault monitors, and device thermal warning and shutdown. Spread spectrum clocking is included for EMI reduction.

 

This driver is suitable for various automotive applications, including brushed DC motors, solenoids, relays, and power modules like window lifts, sunroofs, seats, and trunk/lift gates.
