DESCRIPTION

· The S-19680 Series is a high side switch with current monitor function, developed using CMOS technology.

· It supplies voltage to the load connected to the OUT pin when the Pch output transistor is turned on.

· It monitors and limits the current from the VIN pin to the OUT pin using two external resistors.

· It detects short-circuit or open status of the load and outputs an alarm signal.

· It includes an ON/OFF circuit to control the Pch output transistor and a thermal shutdown circuit to prevent overheating.

· The thermal shutdown circuit can be selected as hysteresis type or latch type.

· ABLIC Inc. provides FIT rate calculations based on actual customer usage conditions for functional safety design support.
