[Outline]

In various CPU systems or other logic systems, when the time of a power supply injection and a power supply are severed for a moment, this IC detects supply voltage and applies reset to a system.
To ±1.5% of detection voltage accuracy of the conventional product, a maximum of ±0.5% of super-high precision is realized, and it is more suitable for battery detection etc.
The accuracy from elegance is conventionally raised from +100/-50% to ±10% also about delay resistance.
Moreover, the component-side product is realizing the small space using SSON-4.

[Features]

1. High Accuracy	±0.5% typ. /2.0~6.0V ±0.8% typ. /0.8~1.9V
2. Super low supply current	0.35µA typ.
3. Component-side product	1.10×1.40mm (SSON-4)
4. Operating-temperature range	-40~+105ºC
5. Delay resistance accuracy	10MΩ±10%
6. Detecting voltage rank	0.8~6.0V (0.1V step)
