SY6982E--效率高,2A,双电池升压锂离子电池充电器 |
功能说明: |
SY6982E is a 3.6-5.5V IN , 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. |
