Product Overview
The DRV8320 is a Texas Instruments 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 operating range. Adjustable Smart Gate Drive supports peak source current from 10 mA to 1 A and peak sink current from 20 mA to 2 A.
Integrated gate driver supplies support 100% PWM duty cycle operation, with a charge pump generating the high-side gate drive voltage and an internal linear regulator generating the low-side gate drive voltage. Logic inputs support 1.8 V, 3.3 V, and 5 V levels, and the DVDD regulator provides 3.3 V with 30 mA external source capability.
DRV8320 is available with hardware or SPI interface options: DRV8320H uses a hardware interface and DRV8320S uses SPI. The DRV8320 device comparison lists no buck regulator and zero current sense amplifiers. Assembly-related recommendations include a 47 nF VM-rated charge pump capacitor and a 1 µF, 6.3 V DVDD capacitor. Fault and protection coverage includes nFAULT indication, undervoltage, MOSFET overcurrent, gate driver fault, thermal warning, and thermal shutdown functions.
