ADM709MAR Description

Short technical summary and product information.

The ADM709MAR is an integrated circuit from Analog Devices that functions as a precision power supply monitor. It is designed to ensure system stability by generating a reset signal when the supply voltage (VCC) falls below a predetermined threshold. This is crucial during power-up, power-down, and brownout events, holding a microprocessor (µP) in reset.

 

This device offers a reset voltage threshold of 4.4V, suitable for monitoring +5V and +3.3V power supplies. Upon power-up, the RESET output remains low for a minimum of 140ms after VCC rises above the threshold, providing a sufficient reset pulse. The RESET output remains operational even with VCC as low as 1V.

 

The ADM709MAR is available in an 8-pin SOIC package, designed for surface mount applications. Its operating temperature range is from -40°C to +85°C (TA), making it suitable for industrial environments. The device monitors a single voltage supply and provides an active low, push-pull totem pole reset output.

 

Key features include a low quiescent current and a low-cost design, making it an effective solution for critical microprocessor monitoring in various systems, including computers, controllers, and automotive applications.
