Automotive, 125°C Operation, 10 V Voltage Detector with Delay Function (External Delay Time Setting) S-19101xxxA Series

The S-19101xxxA 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). 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 +125°C. Two output forms Nch open-drain and CMOS output are available.
Compared with conventional CMOS voltage detectors, the S-19101xxxA Series has super-low current consumption and small packages.

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
