供应台湾致新 G2279RE1U 锂电池线性充电器

　　General Description

　　The G2278 is a standalone linear Li-Ion battery charger with a complete trickle-charge, constant-current and constant-voltage charge loop.

　　No external power MOSFET, sense resistor and blocking diode is required due to internal power MOSFET architecture. The charge voltage is regulated at 4.2V, and the charge current is programmable by an external resistor. The pre-charge current and termination current threshold are programmed via an external resistor on the G2278, the open drain NMOS /CHRG pin would be automatic weakly pull low and terminating the charge loop and /PG pin would be automatic strongly pull low at power ready.

　　Other features include under voltage lockout, automatic recharge, over temperature protection and acharge status indication pin.
