MAX1773A Datasheet Power Source Selector

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX1773/MAX1773A EVALUATION KIT AVAILABLE Power Source Selector for Dual-Battery Systems.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX1773/MAX1773A highly integrated ICs serve as the control logic for a system with multiple power sources.

They directly drive external P-channel MOSFETs to select from an AC adapter and dual battery sources for charge and discharge.

The selection is made based on the presence of the power sources and the state of the batteries.
