Application Note: SY6924 High Efficiency, 2.5A, Multi-Cell Li-Ion Battery Charger General Description SY6924 is a 4-14V input, 2.5A multi-cell Li-Ion battery step-down charger. The charge current up to 2.5A can be programmed by using the external resistor for different portable applications. It also has a programmable charge timeout and adaptive input power limit for safety battery charge operation. It consists of 16V rating reverse blocking FET and power switching FETs with extremely low ON resistance to achieve high charge efficiency and simple peripheral circuit design. SY6924 along with small QFN3×3 footprint provides small PCB area application.
