NCP3800V Datasheet, PDF (1/15 Pages) ON Semiconductor – SMBus Level 2 Battery Charger

NCP3800V
SMBus Level 2 Battery
Charger
The NCP3800V is a highly integrated Lithium−ion battery charger
controller which can be programmed via the SMBus. It can be used to
charge smart batteries and includes three loops for output voltage,
output current and input current. External switch FETs are driven by
internal charge pump drivers.
