[Outline]
This is a reset IC with an independent voltage detection monitor terminal VS and VDD terminal.
The IC power supply is separate and so, even if the monitor voltage VS is low, the output does not become unstable at the operation limit like conventional reset ICs. Instead it maintains low-level operation.
This IC is particularly suitable for low-voltage (1V type) power monitoring. It has an accuracy of 1.5% and an ultralow current consumption of 0.35 µA typ. and otherwise offers characteristics resembling those of conventional IC reset ICs.

[Features]
1. IC power supply terminal VDD and voltage-detecting monitor terminal VS are independent of each other.
2. High accuracy voltage detection
1.5% (Ta=25ºC)
3. Ultra low current consumption
0.35 µA typ.
4. Low operating supply voltage
0.7~10.0V
5. Operating temperature range
-40~+105C


[Packages]


[Applications]
1. Reset circuits for CPUs and MPUs
2. Reset circuits for logic circuits
3. Battery voltage check circuits
