Analog Devices ADM8611/ADM8616/ADM8617/ADM8618 Supervisory Circuit Datasheet
This datasheet covers the ADM8611, ADM8616, ADM8617 and ADM8618 supervisory circuits from Analog Devices. They monitor power supply voltage levels and code execution integrity in microprocessor-based systems, generating a power-on-reset signal when the supply voltage rises to a preset threshold. The ADM8611 adds a debounced manual reset input, while the ADM8616 through ADM8618 include an on-chip watchdog timer that resets the microprocessor if it fails to strobe within a preset timeout period.
The parts differ in reset output configuration: push-pull active-low, open-drain active-low, or push-pull active-high. Each part is offered in nine reset threshold options from 1.58 V to 4.63 V, is specified over -40°C to +85°C, and comes in a 4-lead SC70 package. The document includes a selection table, specifications, absolute maximum ratings, pin descriptions, outline dimensions and ordering guides for all four parts.

Questions answered in these manuals
What is the difference between the ADM8611 and the ADM8616/ADM8617/ADM8618?
The ADM8611 has a debounced manual reset input for an external push-button or logic signal. The ADM8616, ADM8617 and ADM8618 have an on-chip watchdog timer instead.
