NCP1218 Product details

Description

Pin Name Description 1 Skip/Latch This pin provides a latch input to permanently disable the device under a fault condition.It also allows the user to adjust the skip threshold.A resistor between this pin and GND provides noise immunity to the latch input and sets the skip threshold.The voltage on this pin is determined by the combination of the internal voltage divider and the external resistor to ground.The default skip threshold is 1.1 V (typical) if no external resistor is used.An i
