• Manufacturer Part Number: ADM6821LART-RL
• Description: Low Voltage Supervisory Circuits with Watchdog & Manual Reset in 5-Lead SOT-23
• Manufacturer: AD [Analog Devices]

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.

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.
