Automotive, 125°C Operation, 36 V, Voltage Detector with Fast Detection Response, SENSE Pin Reverse Connection Protection, Delay Function (External Delay Time Setting) S-19114xxxA Series

The industry's Fastest* Detection Response Improves the safety S-19114xxxA Series

This IC, developed using CMOS technology, is a high-accuracy voltage detector. The detection voltage and release voltage are fixed internally with an accuracy of ±1.5%.
Since the detection response time is as fast as 10 μs max., voltage abnormalities can be detected and notified quickly. Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even if the SENSE pin voltage (VSENSE) falls to 0 V. The SENSE pin also has a built-in reverse connection protection circuit that reduces current in the SENSE pin during a reverse connection.
The release signal can be delayed by setting a capacitor externally, and the release delay time accuracy is ±20% (CD = 3.3 nF). The output form is Nch open-drain output.

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.
