SGM802

Low-Power, SC70/SOT µP Reset Circuit with

Capacitor-Adjustable Reset Timeout Delay

GENERAL DESCRIPTION

FEATURES

The SGM802 low-power micro-processor supervisor

circuit monitors system voltages from 1.6V to 5V. This

device performs a single function: it asserts a reset signal

whenever the V_CCsupply voltage falls below its reset

threshold. The reset output remains asserted for the

reset timeout period after V_CCrises above the reset

threshold. The reset timeout is externally set by a

capacitor to provide more flexibility.



Monitor System Voltages from 1.6V to 5V

Capacitor-Adjustable Reset Timeout Period

Low Quiescent Current (3µA TYP)

Push-Pull RESET Output Option

Guaranteed RESET Valid to V_CC= 1V

Immune to Short V_CCTransients

Available in Green SC70-4 (R) and SOT-143

Packages

The SGM802 has an active-high, push-pull reset output.

It is available in Green SC70-4 (R) and SOT-143

packages. The SGM802 is specified over an ambient

temperature range of -40℃ to +85℃.
