The NE56605-42 is designed to generate a reset signal, at a threshold voltage of 4.2 V, 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. The NE56605-42 has a built-in Watchdog Timer to monitor the microprocessor and ensure it is operating properly. Any abnormal system operations due to microprocessor malfunctions are terminated by the watchdog's generating a system reset. The NE56605-42 has a watchdog monitoring time of 10 ms (typical).
The NE56605-42 is offered in the SO8 surface mount package.
