【文字介紹】

•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 240 ms. 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 while the SGM810 provides an active high signal output.
•Eight reset threshold voltage options are available suitable for monitoring 1.8V, 2.5V, 3V, 3.3V and 5V supply voltages.
