... Philips Semiconductors System reset with Watchdog timer GENERAL DESCRIPTION The NE56625-20 is comprised of a power-on reset, a Watchdog timer and low battery detection circuit. The NE56625 is designed to generate an Active-LOW reset signal for a variety of microprocessor and logic systems. Accurate reset signals are generated during momentary power interruptions or whenever power supply voltages sag to intolerable levels ...

... If the microprocessor clock signal ceases or becomes erratic, the NE56625-20 outputs a reset signal to the microprocessor. If the microprocessor supply voltage sags to 2.0 volts or less, the NE56625-20 outputs a reset signal for the duration of the supply voltage deficiency. The Undervoltage Reset signal allows the microprocessor to shut down in an orderly manner to avoid system corruption ...
