Description
SS809/810G 3-Pin Microprocessor Reset Circuits .
The SS809G and SS810G are low-power microprocessor (µP) supervisory circuits used to monitor power supplies in µP and digital systems.
Features
* Ultra-low supply current 1µA (typ. ) Guaranteed reset valid to Vcc=0.9V Available in three output types: Open-drain active low (SS809N-xxGx) Push-pull active low (SS809-xxGx) Push-pull active high (SS810-xxGx) Power-on reset pulse width min. 140ms Internally fixed threshold 2.3V, 2.6V, 2.9V, 3.1V, 4.
Applications
* with Vcc ranging from 6.0V down to 0.9V. The reset signal lasts for a minimum period of 140ms whenever the VCC supply voltage falls below a preset threshold. Both the SS809G and SS810G were designed with a reset comparator to help identify invalid signals lasting less than 140ms. The only difference
