VOLTAGE DETECTOR WITH SENSE PIN
Rev.1.1_00
The S-1002 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed
internally with an accuracy of ±1.0% (VDET(S) 2.2 V). It operates with current consumption of 500 nA typ.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even
if the SENSE pin falls to 0 V.
Two output forms Nch open-drain output and CMOS output are available.
Features
Detection voltage:
1.0 V to 5.0 V (0.1 V step)
Detection voltage accuracy:
±1.0% (2.2 V ≤ −VDET(S) 5.0 V)
±22 mV (1.0 V ≤ −VDET(S) < 2.2 V)
Current consumption:
500 nA typ.
Operation voltage range:
0.95 V to 10.0 V
Hysteresis width:
5% ± 2%
Output form:
Nch open-drain output (Active "L")
CMOS output (Active "L")
Operation temperature range: Ta = 40°C to +85°C
Lead-free (Sn 100%), halogen-free
Applications
Power supply monitor for microcomputer and reset for CPU
Constant voltage power supply monitor for TV, Blu-ray recorder and home appliance
Power supply monitor for portable devices such as notebook PC, digital still camera and mobile phone
