FOR AUTOMOTIVE 105°C OPERATION CURRENT MONITOR
HIGH SIDE SWITCH
Rev.1.2_01
The S-19680 Series, developed by using CMOS technology, is a high side switch with the current monitor function.
When the Pch output transistor is turned on, voltage is supplied to the load connected to the OUT pin. Monitoring the
current which flows from the VIN pin to the OUT pin by using two external resistors, the S-19680 Series limits the current
so that it does not exceed the set value. Depending on the monitored current value, the S-19680 Series detects the
short-circuit status or the open status of the load connected to the OUT pin, and outputs an alarm signal.
In addition, the S-19680 Series has the ON / OFF circuit to control the Pch output transistor's status, ON and OFF, and the
thermal shutdown circuit to limit overheating. The hysteresis type or latch type can be selected for the thermal shutdown
circuit.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to ABLIC Inc. is indispensable.
