DESCRIPTION

The MPQ6411 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 MPQ6411 in a defined time

window cyclically. A missing or fault trigger

signal causes the watchdog to reset the MCU.

The MPQ6411 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 MPQ6411 is available in SOIC8 package.
