MAX809ZEXR+T Description

Short technical summary and product information.

The MAX809ZEXR+T from Analog Devices is a microprocessor supervisory circuit used to monitor power supplies in digital systems. It provides reliable power monitoring by asserting a reset signal when the VCC supply voltage drops below a preset threshold, maintaining the reset for at least 140ms after VCC rises above the threshold.

 

This device operates with a single voltage monitoring channel and features an active-low, push-pull output. The operating voltage threshold is 2.32V, and the reset timeout is a minimum of 140ms. It is designed to ignore fast transients on VCC and guarantees a valid reset state for VCC down to 1V.

 

The MAX809ZEXR+T is available in a compact SC-70-3 package, suitable for surface mount applications. Its low supply current makes it ideal for portable and battery-powered equipment. The operating temperature range is -40°C to 125°C (TA).
