产品描述
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   output remains operational with V CC as low as 1V. The SGM803/SGM809 provides an active low reset signal ( ) 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 V CC .
 
The low supply current of typically 13μA makes the SGM803/SGM809/SGM810 ideal for use in portable, battery operated equipment. All are specified over the extended -40 °С to + 125 °С temperature range.
