NCP81178 General Description

Pin No. Pin Name Description 1 SDDET Primary shutdown detection. When the voltage on this pin exceeds the shutdown threshold, the driver shuts down. If valid PWM pulses resume and VCC is above UVLO threshold, the driver will go through a restart process. 2 RRAMP Ramp slope setting for the.
