Overview
The SGM803B/SGM809B/SGM810B 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 nRESET output remains operational with VCC as low as 1V. The SGM803B and SGM809B provide an active low reset signal (nRESET) while the SGM810B provides an active high signal (RESET) output. The SGM809B/ SGM810B have push-pull outputs, whereas the SGM803B has an open-drain output, which requires an external pull-up resistor. Five reset threshold voltage options are available, suitable for monitoring 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 of typically 300nA makes the SGM803B/SGM809B/SGM810B ideal for use in portable, battery operated equipment. All are specified over the extended -40°C to +125°C temperature range.
