MANUAL RESET BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) HIGH-ACCURACY VOLTAGE DETECTOR
Rev.1.0_00
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.
