SY6982E,
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. |
