DRV8703QRHBRQ1 Description

Short technical summary and product information.

The DRV8703QRHBRQ1 from Texas Instruments is an automotive-qualified H-bridge gate driver designed for bidirectional brushed DC motor control. It supports a wide operating supply voltage range of 5.5V to 45V.

 

This device features an integrated charge pump for 100% duty cycle support and an internal sense amplifier for adjustable current regulation. It offers multiple control interface options, including PH/EN, Independent H-Bridge, and PWM Serial Interface for configuration. The gate driver architecture is smart, with adjustable slew-rate control and independent control of each half-bridge.

 

Protection features include supply undervoltage lockout (UVLO), charge-pump undervoltage lockout (CPUV), overcurrent protection (OCP), gate-driver fault (GDF), and thermal shutdown (TSD). A watchdog timer and fault-condition output (nFAULT) are also included.

 

The DRV8703QRHBRQ1 is supplied in a 32-VQFN package with surface mount, wettable flank mounting. It operates within an ambient temperature range of -40°C to 125°C.
