ADM705AR Description

Short technical summary and product information.

The ADM705AR is a microprocessor supervisory circuit designed by Analog Devices for monitoring 5V power supplies and microprocessor activity. It provides essential functions such as power-supply monitoring that generates a reset output during power-up, power-down, and brownout conditions. The reset output remains operational even when VCC is as low as 1V.

 

Key electrical specifications include a quiescent current of 190μA and a reset pulse width of 200ms. The ADM705AR includes a precision supply voltage monitor with a nominal threshold of 4.65V for the ADM705/ADM707 series. It also features a 1.25V threshold detector for power-fail or low-battery warnings, and an independent watchdog timer with a 1.60-second timeout for the ADM705/ADM706 models.

 

This supervisory circuit is suitable for critical microprocessor supply monitoring in various applications, including microprocessor systems, computers, controllers, and intelligent instruments. Its robust design ensures reliable operation and protection for sensitive electronic systems.
