Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
Overtemperature limits are guaranteed by design, production testing performed at +25°C only.
Note 2:
WDO
is low when V
CC
falls below the undervoltage threshold. When V
CC
rises above the undervoltage threshold,
WDO
goes
high after the watchdog pulse period.
Note 3:
Watchdog pulse period occurs when the watchdog times out or after V
CC
rises above the undervoltage threshold.
Note 4:
The
WDO
short-circuit current is the maximum pullup current when
WDO
is driven low.
Note 5:
WDI is internally serviced within the watchdog period if WDI is left unconnected.
Note 6:
The WDI input current is specified as the average input current when the WDI input is driven high or low. The WDI input is
designed to drive a three-stated output device with a 10μA maximum leakage current and a maximum capacitive load of
200pF. This output device must be able to source and sink at least 200μA when active.
