Description
The FAN5201 is a smart battery charger IC controller for
Li+ and Ni based battery chemistries. The charger (slave)
together with the host controller and smart battery constitutes
a smart battery system that communicates via the SMBus
protocol, a two wire serial communication system.
An innovative power control loop allows operation from line
power and battery charging (with residual power) without
exceeding the maximum input power programmed according
to the AC adapter power rating.
The FAN5201 is available in one SSOP24 package.
