General Description
Benefits and Features
The MAX77960B/MAX77961B are high-performance
wide-input 3A (MAX77960B)/6A (MAX77961B) buck-
boost chargers 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) acces-
sories. The devices 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 cur-
rent limit. The devices are highly flexible and programma-

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.
