The S-1003 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed
internally with an accuracy of
±1.0% (−VDET ≥ 2.2 V). It operates with current consumption of 500 nA typ.
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.
