Overview
SGM811/SGM812 Microprocessor Supervisory Circuits with Manual Reset Input
GENERAL DESCRIPTION
The SGM811/SGM812 supervisory circuits monitor the power supply voltage in microprocessor and digital systems.
The SGM811/SGM812 are designed to monitor eight 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, powerdown 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 nRESET output remains operational with VCC as low as 1V.
The SGM811 provides an a...
