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...
