SGM804 Datasheet, PDF (1/11 Pages) SG Micro Corp – Capacitor-Adjustable Reset Timeout Delay

SGM804
Low-Power, SOT µP Reset Circuit with
Capacitor-Adjustable Reset Timeout Delay
GENERAL DESCRIPTION
The SGM804 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_CC supply voltage falls below its reset
threshold. The reset output remains asserted for the
reset timeout period after V_CC rises above the reset
threshold. The reset timeout is externally set by a
capacitor to provide more flexibility.
FEATURES
 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_CC Transients
 Available in Green SOT-23-5 Package
The SGM804 has an active-low, push-pull reset output. It
is available in Green SOT-23-5 package and is specified
over an ambient temperature range of -40℃ to +85℃.
