The S-1003 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed

internally with an accuracy of

The release signal can be delayed by setting a capacitor externally. Delay time accuracy is

±15%.

Moreover, since the S-1003 Series includes the manual reset function, the reset signal can be also output forcibly.

Two output forms Nch open-drain output and CMOS output are available.
