com A4810A/B HIGH PRECISION BUILT-IN DELAY CIRCUIT FULL TEMP RANGE, ULTRA-LOW VOLTAGE DETECTOR DESCRIPTION FEATURES The A4810A/B microprocessor supervisory circuit can be used to monitor the power supplies in microprocessor and digital systems.
It provides a reset to the microprocessor during power-up, power-down, and brown-out conditions.
  The function of the A4810A/B is to monitor the VDD supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold.
The reset signal remains asserted for 250ms after VDD rises above the threshold.
The A4810A/B has an active-low /RESET output.
