Automotive, 125°C Operation, 10 V Voltage Detector with Delay Function (External Delay Time Setting) S-19100xxxA Series

The S-19100xxxA Series, developed by using CMOS technology, is a voltage detector IC for automotive 125°C operation.
The detection voltage is fixed internally with an accuracy of ±3.0% (-Vdet = 2.4 V). It operates with current consumption of 270 nA typ.
The release signal can be delayed by setting a capacitor externally, and the delay time accuracy at Ta = +25°C is ±15%.
The operation temperature range is Ta = -40°C to +125°C. Two output forms Nch open-drain and CMOS output are available.
Compared with conventional CMOS voltage detectors, the S-19100xxxA Series has super-low current consumption and small packages.

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.
