Description

The MAX6339MUT+T is a precision quad voltage monitor with microprocessor (µP) supervisory reset timing. It can monitor up to four system supply voltages without the need for any external components. If any supply voltage drops below its preset threshold, the MAX6339MUT+T asserts a single reset. This component greatly reduces system size and component count while improving reliability compared to separate ICs or discrete components.
