DESCRIPTION

The MP6411 is a windowed watchdog timer. It

is used to reset and monitor the microcontroller.

In normal operation, the MCU sends a trigger

signal to the MP6411 in a defined time window

cyclically. A missing or fault trigger signal

causes the watchdog to reset the MCU.

The MP6411 provides a reset signal (low-level

voltage) to the MCU during power-up or under

voltage. Its power supply (VCC) has 5V and

3.3V options.

By setting MODE to high or low, the watchdog

operates in long window mode or short window

mode; the window is programmable.

The MP6411 is available in SOIC8 package.
