ADM809-5S Datasheet (Analog Devices) - Microprocessor Supervisory Circuit

ADM809-5S, Microprocessor Supervisory Circuit

The supervisory circuit of the ADM809-5L/ADM809-5S monitors the power supply voltage in microprocessor systems.

It provides a reset output during power-up, power-down, and brownout conditions.

On power-up, an internal timer holds reset asserted for 55 ms.

This holds the microprocessor in a reset sta
