SS809 - 3-Pin Microprocessor Reset Circuits

Description

The SS809G and SS810G are low-power microprocessor (µP) supervisory circuits used to monitor power supplies in µP and digital systems.

They improve circuit reliability and reduce cost by eliminating external components.

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, 4.0V, 4.4V, 4.6V Tight voltage threshold tolerance: 1.5% Packaged in RoHS-compliant SOT-23-3 These devices provide valid signals in.

SS809/810G 3-Pin Microprocessor Reset Circuits 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, 4.0V, 4.4V, 4.6V Tight voltage threshold tolerance: 1.5% Packaged in RoHS-compliant SOT-23-3 These devices provide valid signals in 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.
