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.
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.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. Exceeding the maximum allowable powe
r
dissipation will cause an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
