SY6982C中文资料High Efficiency, 2A, Two-Cell Boost Li-Ion Battery Charger数据手册Silergy规格书

描述 Description

SY6982C is a 3.0-5.5VIN, 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 and adaptive input current limit with selectable threshold for safety battery charge operation. SY6982C 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.

SY6982C along with small QFN3x3 footprint provides small PCB area application.
