3 Description
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.
