Overview
SGM803/SGM809/SGM810 Microprocessor Supervisory Circuit in 3-Pin SOT-23 GENERAL DESCRIPTION The SGM803/SGM809/SGM810 supervisory circuits monitor the power supply voltage in microprocessor and digital systems.
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 VCC as low as 1V.
The SGM803/ SGM809 provides an active low reset signal ( RESET ) while the SGM810 provides an active high signal (RESET) output.
The SGM809/SGM810 has push-pull outputs, whereas the SGM803 has an open-drain output, which requires an external pull-up resistor.
Eight reset threshold voltage options are available suitable for monitoring 1.
8V, 2.
5V, 3V, 3.
3V and 5V supply voltages.
The reset comparator features built-in glitch immunity, making it immune to fast transients on VCC.
The low supply current ...
