深圳现货供应-G2267TO1U-TSOT-23-5 单芯锂离子电池线性充电器G2267，台湾致新进口原装芯片

品牌：GMT致新

型号：G2267TO1U

封装：TSOT-23-5

General Description
The G2267 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. After the final regulation voltage is reached and the charge current drops to 1/10th the programmed charge current, the open drain NMOS /CHRG pin would be automatic weakly pull low and terminating the charge loop.
Other features include under voltage lockout, automatic recharge, over temperature protection and a charge status indication pin.
