Pin Descriptions
Pin Number Pin Name Function
1 GND Signal ground. Current return for driver and control circuits
2 FB Feedback. Directly connected to the opto-coupler
3 CTRL
Latch trigger if this pin voltage drops below a threshold or over another threshold, leave CTRL pin
open if this function is not needed. Connecting a NTC thermistor to GND can achieve OTP
protection
4 SENSE Current Sense
5 VCC Supply voltage of driver and control circuits
6 GATE Gate driver output
