Description
Active-Low Reset Output, which is asserted whenever V
CC
is below the reset.threshold, V
TH
.
Push-Pull Output Stage for ADM8616.
Open-Drain Output Stage for ADM8617.
Active-High, Push-Pull Reset Output.
Manual Reset Input. This is an active-low input which, when forced low for at least 1μs,
generates a reset.
Features a 52k internal pull-up.
Watchdog Input. Generates a reset if the logic level 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. Leave floating to disable the watchdog timer.

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.
