The MIC803 is a single-voltage supervisor with open-drain reset output that provides accurate power supply monitoring and reset generation in microprocessor based systems. The function of the device is to assert a reset signal if the power supply voltage drops below the Reset Threshold voltage, and retain this reset for the Reset Timeout Period once the power supply increases above the Reset Threshold voltage.The MIC803 consumes only 4.5μA of supply current and offers three reset delay periods of 20ms, 140ms and 1120ms (min).
