Product Overview
The DRV8323 from Texas Instruments is a three-phase smart gate driver for Power_Management designs using external N-channel MOSFETs. Its triple half-bridge gate driver drives three high-side and three low-side MOSFETs from a 6 to 60 V gate driver supply. Integrated gate driver supplies include a charge pump for the high-side gate drive voltage and a linear regulator for the low-side gate drive voltage, supporting 100% PWM duty cycle operation.
Gate drive strength is adjustable, with 10 mA to 1 A peak source current and 20 mA to 2 A peak sink current. Input PWM control modes include 6x, 3x, 1x, and independent operation, and logic inputs are compatible with 1.8 V, 3.3 V, and 5 V logic levels. DRV8323H uses a hardware interface, while DRV8323S uses an SPI interface.
The DRV8323 variant integrates three low-side current sense amplifiers with 5, 10, 20, and 40 V/V gain settings and bidirectional or unidirectional current sense operation. It is supplied in a WQFN (40), 6.00 mm × 6.00 mm package. Protection functions include VM UVLO, charge pump undervoltage, MOSFET overcurrent, MOSFET short circuit, gate driver fault, and overtemperature, with fault indication through the nFAULT pin.
