至为芯科技XB6166IS小容量锂电池充电保护IC
XB6166I2S DFN2X2 二合一保护 ２.过流小过流１A（小电池自身内阻大，短路电流小１－２A，市面上保护IC大多过流是３A。在小电池上起不到短路保护作用）。.通过放自恢复保护IC的静态电流在1-2uA. 这保证了电池在过放后长期不用，也不会对电芯造成损害。
封装：DFN2x2-6
GENERAL DESCRIPTION
The XB6166I2S product is a high integration solution for lithiumion/ polymer battery protection.
XB6166I2S contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits.
XB6166I2S is put into an ultra-small DFN2X2-6 package and only one external component makes it an ideal solution in limited space of battery pack.
XB6166I2S has all the protection functions required in the battery application including overcharging, overdischarging, overcurrent and load short circuiting protection etc. The accurate overcharging detection voltage ensures safe and full utilization charging.
The low standby current drains little current from the cell while in storage.
The device is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Poly battery-powered information appliances requiring longterm battery life.
