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.
