Power Source Selector for  
Dual-Battery Systems  
General Description  
Features  
o Patented† 7-MOSFET Topology Offers Low-Cost  
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 bat-  
tery 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.  
Solution  
o Automatically Detects and Responds to:  
Low Battery Voltage Condition  
Battery Insertion and Removal  
AC Adapter Presence  
o Direct Drive of P-Channel MOSFETs  
o Simplifies Power Management µP Firmware  
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 prob-  
lem. The MAX1773/MAX1773A provide most of the power  
source monitoring and selection, freeing the system power  
management microprocessor (µP) for other tasks. This not  
only simplifies development of the power management  
firmware for the µP but also allows the µP to enter standby,  
thereby reducing system power consumption.  
o Extends Battery Life by Allowing Power  
Management µP to Enter Standby  
o 4.75V to 28V AC Adapter Input Voltage Range  
o Integrated LDO with 1mA Drive Capability  
o Small Footprint 20-Pin TSSOP Package  
Ordering Information  
The MAX1773A is recommended for new designs.
