SGM802 fiche technique
SGM802
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.
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 VCC = 1V
Immune to Short VCC Transients
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 -40to +85.
