OZ8660LN Datasheet – Single Battery Charger Controller
Package QFN 40 Pin Type
OZ8660LN overview
OZ8660 is a high performance battery charge controller with four power MOSFETs, from power switching and selector, integrated into one package. It has input and charging current sensing, and programmable wake-up threshold with associated logic and drivers to manage the integrated system’s power path. It can operate under the supervision of a host microcontroller, and provides complete battery charging control for single battery portable systems.
OZ8660 uses two high-side current sensors. When charging with the system ON, it dynamically allocates all remaining AC adapter current not used by the system to the charger, achieving the shortest possible charging time.
