MAX813 Microprocessor Supervisory Circuit Datasheet

The MAX813 is a microprocessor monitor for monitoring the system voltage of a microprocessor system. The MAX813 will provide a RESET signal (Active High) when the voltage falls below 4.65V, the RESET signal is held for at least 200ms when the voltage returns to the correct operating voltage. The MAX813 also includes a watchdog timer, which needs to be toggled every 1.6 seconds. A power fail warning output is also provided for low battery detection.
