AMS26

TYPICAL APPLICATIONS

CPU Reset Circuit

Input Voltage to AMS26 is the same as the input voltage to CPU.

Input Voltage to AMS26 is different from the input voltage to CPU.

Output Delay Time Circuit

Voltage Level Indicator Circuit (lighted when the power runs out)

Detector Threshold Changing Circuit
