The DRV8343SPHPRQ1 from Texas Instruments is an automotive-qualified 3-phase smart gate driver. It is designed to drive 3 high-side and 3 low-side N-channel MOSFETs, supporting Brushless DC (BLDC) motors.
Key electrical specifications include a wide supply voltage range from 5.5V to 65V and an operating temperature range of -40°C to 125°C. The device features an SPI interface for control and configuration, along with multiple PWM modes (6x, 3x, 1x, and independent). It provides adjustable gate drive currents with peak source current up to 1A and peak sink current up to 2A.
Integrated into the DRV8343SPHPRQ1 are three current sense amplifiers with selectable gain (5, 10, 20, 40 V/V) for accurate current monitoring. It also includes a 3.3V linear voltage regulator with 30mA output capability. The device incorporates various protection features such as VM undervoltage lockout (UVLO), short to battery/ground, MOSFET overcurrent protection (OCP), and thermal warning/shutdown.
Packaged in a 48-HTQFP, the DRV8343SPHPRQ1 is suitable for surface mount applications. Its AEC-Q100 qualification makes it ideal for demanding automotive environments.
