SGM802

Low-Power, SC70/SOT μP Reset Circuit with Capacitor-Adjustable Reset Timeout Delay
 
Low-Power, SC70/SOT μP Reset Circuit with Capacitor-Adjustable Reset Timeout Delay
GENERAL DESCRIPTION

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 VCC supply voltage falls below its reset threshold. The reset output remains asserted for the reset timeout period after VCC rises above the reset threshold. The reset timeout is externally set by a capacitor to provide more flexibility.

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.
