General Description  
Benefits and Features  
The MAX77960/MAX77961 are high-performance wide-  
input 3A (MAX77960)/6A (MAX77961) buck-boost charg-  
ers with Smart Power Selector™ and operate as a reverse  
buck converter without an additional inductor, allowing the  
ICs to power USB on-the-go (OTG) accessories. The de-  
vices integrate low-loss power switches and provide high  
efficiency, low heat, and fast battery charging in a small  
solution size. The reverse buck has true load disconnect  
and is protected by an adjustable output current limit. The

devices are highly flexible and programmable through I C  
configuration or autonomously through resistor configura-  
tion.

• 100mA to 6A Programmable Constant Current  
Charge  
The battery charger includes the Smart Power Selector to  
accommodate a wide range of battery sizes and system  
loads. The Smart Power Selector allows the system to  
start up smoothly when an input source is available even  
when the battery is deeply discharged (dead battery) or  
missing. For battery safety/authentication reasons, the ICs  
can be configured to keep charging disabled, and allow  
the DC-DC to switch and regulate the SYS voltage. The

system processor can later enable charging using I C  
commands as appropriate. Alternatively, the ICs can be  
configured to automatically start charging.  
Applications

Applications  
● Reverse Buck Mode 5.1V/3A to Support USB OTG  
● JEITA Compliant with NTC Thermistor Monitor  
● 2- and 3-Cell Battery-Powered Devices
