Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

Open-Drain Output Stage for the ADM6822.
Push-Pull Output Stage for the ADM6823/ADM6824/ADM6825.
RESET (ADM6821) Active-High Push-Pull Reset Output.
2 GND Ground.
3
MR (ADM6821/ADM6822/ADM6823) Manual Reset Input. This is an active-low input, which, when forced low for at
least 1 μs, generates a reset. It features a 50 kΩ internal pull-up.
RESET (ADM6824/ADM6825) Active-High Push-Pull Reset Output.
4
WDI
(ADM6821/ADM6822/ADM6823/ADM6824)
Watchdog Input. Generates a reset if the voltage on the pin remains low or high
for the duration of the watchdog timeout. The timer is cleared if a logic transition
occurs on this pin or if a reset is generated.
MR (ADM6825)
Manual Reset Input.
