Description

Active-Low Reset Output, which is asserted whenever VCC is below the reset.threshold,

VTH.

Open-Drain Output Stage for ADM6822.

Push-Pull Output Stage for ADM6823/24/25.

Active-High Reset Output

Ground

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.

Active-High Push-Pull Reset Output.

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.

Manual Reset Input.

Power Supply Voltage being Monitored

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.
