MAX1773A - Power Source Selector

Download the MAX1773A datasheet PDF. This datasheet also covers the MAX1773 variant, as both devices belong to the same power source selector family and are provided as variant models within a single manufacturer datasheet.

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.

MAX1773/MAX1773A EVALUATION KIT AVAILABLE Power Source Selector for Dual-Battery Systems 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. The MAX1773/MAX1773A detect low battery conditions using integrated analog comparators and check for the presence of a battery by using battery thermistor outputs. The MAX1773/MAX1773A are designed for use with a buck topology charger. They provide a simple and easily controlled solution to a difficult analog power control problem.
