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.

*1. −VDET: Actual detection voltage value, −VDET(S): Set detection voltage value (the center value of the detection voltage
range in Table 3 or Table 4.)
*2. VDS: Drain-to-source voltage of the output transistor
*3. The time period from when the pulse voltage of 0.95 V → −VDET(S) + 1.0 V is applied to the VDD pin to when VOUT
reaches VDD × 0.9, after the output pin is pulled up to VDD by the resistance of 100 kΩ.
*4. The temperature change of the detection voltage [mV/°C] is calculated by using the following equation.
Δ − VDET
ΔTa
[mV/°C]*1 = −VDET(S) (typ.)[V]*2 ×
Δ − VDET
