[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
