SY6982E

Application Notes: SY6982E High Efficiency, 2A, Two-Cell Boost Li-Ion Battery Charger General Description SY6982E is a 3.6-5.5VIN, 2A two-cell synchronous boost Li-Ion battery charger integrates 1MHz switching frequency and full protection functions. The charge current up to 2A can be programmed by using the external resistor for different portable applications and indicates the charger current information simultaneous. It also has a programmable charge timeout for safety battery charge operation and a programmable input voltage threshold for adaptive input current limit. SY6982E can disconnect output when there is output short circuit or shutdown happens. It consists of 18V rating FETs with extremely low ON resistance to achieve high charge efficiency and simple peripheral circuit design. SY6982E along with small QFN3x3 footprint provides small PCB area application. Ordering Information SY6982 □(□□)□ Temperature Code Package Code Optional Spec Code Ordering Number SY6...
