Product Details
The MAX705 is a microprocessor monitor for monitoring the
system voltage of a microprocessor system.
The MAX705 will provide a RESET signal 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 MAX705 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.
