MAX821MUS Description

Short technical summary and product information.

The MAX821MUS is a voltage supervisor integrated circuit from Analog Devices / Maxim Integrated, designed for MPU voltage monitoring applications. It features a single monitored voltage with an active-low reset output that is push-pull and totem pole. The reset timeout is adjustable or selectable, providing flexibility in system design.

 

This supervisor operates at a voltage of 4.38V and can function within an operating temperature range of -40°C to 125°C (TA). It is housed in a SOT-143-4 surface mount package, with an alternative standard package designation of TO-253-4, TO-253AA.

 

The MAX821MUS is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1 Unlimited. Its REACH status is unaffected. This component is suitable for applications requiring reliable power-on reset and voltage monitoring.
