Automotive, 105°C Operation, 10 V Voltage Detector with Delay Function (External Delay Time Setting) S-19100xxxH Series

The S-19100xxxH Series, developed by using CMOS technology, is a voltage detector IC for automotive 105°C operation.
The detection voltage is fixed internally with an accuracy of ±2.5% (-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 +105°C. Two output forms Nch open-drain and CMOS output are available.
Compared with conventional CMOS voltage detectors, the S-19100xxxH Series has super-low current consumption and small packages.
