SGM811/SGM812
Microprocessor Supervisory
with Manual Reset Input
GENERAL DESCRIPTION
The SGM811/SGM812 supervisory circuits monitor the
power supply voltage in microprocessor and digital
systems. The SGM811/SGM812 is designed to monitor
seven different voltages; these voltages have been
selected for the effective monitoring of 1.8V, 2.5V, 3V,
3.3V and 5V supply voltage levels.
They provide a reset output during power-up, power-
down and brownout conditions. On power-up, an internal
timer holds reset asserted for 240ms. This holds the
microprocessor in a reset state until conditions have
stabilized. The
RESET
output remains operational with
V
CC
as low as 1V. The SGM811 provides an active low
reset signal (
RESET
) while the SGM812 provides an
active high signal (RESET) output.

The SGM811/SGM812 has a manual reset input. The
manual reset function is very useful, especially if the
circuit in which the SGM811/SGM812 is operating enters
into a state that can only be detected by the user.
Allowing the user to reset a system manually can reduce
the damage or danger that could otherwise be caused by
an out-of-control or locked system. The devices come in
SOT-143 and SOT-23-5 packages.
