The S-19101xxxH 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). The release voltage is set to the same value as the detection voltage, since there is no hysteresis width. 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-19101xxxH Series has super-low current consumption and small packages.
