RESET ICs INDEX	\| HTML \| PDF \|

[Outline]

This IC functions in a variety of CPU systems and other logic systems, to detect supply voltage and reset the system accurately when the power is turned on or interrupted. To ±1.5% of detection voltage accuracy of the conventional models, a maximum of ±0.5% of super-high precisionis realized, and it is more suitable for battery detection etc. Moreover, the mounting area signifi cantly contributes to space saving using the SSON package.

[Features]

1. Ultra-high accuracy	±0.5%/2.0~6.0V ±0.8%/0.8~1.9V
2. Ultra-low current consumption	0.25µA typ.
3. Ultra-small package	1.10×1.40mm (SSON-4)
4. Operating temperature range	-40~+105ºC
5. Detecting voltage rank	0.8~6.0V (0.1V step)
6. Output configuration	PST81XX series ··· CMOS output PST82XX series ··· Open drain output

[Packages]

[Applications]

1. Reset circuits for microcomputers, CPUs and MPUs
2. Reset circuits for logic circuits
3. Battery voltage check circuits
4. Back-up power supply switching circuits
