MAX1773 Datasheet (Maxim) - Power Source Selector

MAX1773, Power Source Selector

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 sour
