Standard Voltage Detector
Description
The function of this low reset Type IC is to accurately reset systems after detecting the supply voltage at the time
of switching power on and instantaneous power off in various CPU and other logic system. Further, this IC, with
its super low consumption current is most suited as a voltage check circuit for a number of products which use
batteries.
Features
• Super low current consumption (ICCL = 1.0uA Typ.)
• High current of output transistor (IOL=20mA Typ.)
• Hysteresis circuit built in (VS=100mV Typ.)
• It has on delay function to supplement the constant of outer C and R.
Applications
• Reset circuits for microcomputers, CPU and MPU.
• Reset circuit for logic circuitry.
• Battery voltage check circuit.
• Circuit for changing over to backup battery.
• Level detecting circuit.
Ordering Information
Type NO.
