The DRV816x devices are half-bridge gate drivers capable of driving high-side and low-side N-channel MOSFETs. The gate drive voltages are generated from the GVDD supply pin and the integrated bootstrap circuit is used to drive the high-side FET up to 102V drain. The Smart Gate Drive architecture supports 16-level (48 combination) gate drive peak current up to 1A source and 2A sink, and a built-in timing control of gate drive current. The devices can be used to drive various types of loads including brushless/brushed DC motors, PMSM, stepper motors, SRM, and solenoids.

Internal protection functions are provided for supply undervoltage, FET over-current, and die over temperature. The nFAULT pin indicates fault events detected by the protection features. The nDRVOFF pin initiates power stage shutdown independent from PWM control. The DRV8162 and DRV8162L devices offer split power supply architecture to assist safe torque off (STO) function.

Many device parameters including gate drive current, dead time, PWM control interface, and over current detection are configurable with a few passive components connected to device pins. An integrated low-side current sense amplifier (DRV8161) provides current measurement information back to the controller.
