The DRV8714SQRHARQ1 is an AEC-Q100 Grade 1 automotive four-channel half-bridge smart gate driver from Texas Instruments, packaged in 40-pin VQFN (RHA) tape-and-reel form, supporting 4.9V to 37V operating supply with 40V absolute maximum rating, driving external N-channel MOSFETs for up to two H-bridges, integrating two wide common-mode inline current-sense amplifiers, SPI and hardware control interfaces, comprehensive fault diagnostics and charge pump, operating from -40°C to +125°C for automotive brushed DC motor and solenoid control systems.
Key Features
● Four independent half-bridge channels configurable as dual H-bridges, with adjustable gate drive slew rate and integrated dead-time handshake to optimize EMC performance and prevent shoot-through.
● Dual wide common-mode current shunt amplifiers with selectable gain of 10,20,40,80 V/V, supporting inline, high-side or low-side current measurement without large external shunt resistors.
● AEC-Q100 Grade 1 automotive qualification, tripler charge pump enabling 100% PWM duty cycle, 5µA ultra-low sleep current and dedicated brake function.
● Dual control modes including SPI for register configuration and full diagnostics, plus simple hardware GPIO/PH/EN/PWM interface for low-pin-count MCU connection.
● Built-in VDS overcurrent monitoring, gate fault detection, open-load detection, thermal shutdown, watchdog timer and nFAULT interrupt output for robust system safety.

FAQ
Q: What key design considerations apply to DRV8714SQRHARQ1?
A: Select matched external power MOSFETs, place power loop traces short for low noise, add adequate gate resistor for slew rate tuning, and configure SPI registers carefully to enable required protection and diagnostic features.
