過充4.3V可選,過放2.8V,充電過流3.3A,放電過流3.4A,持續(xù)放電電流2A，DFN2*2封裝，適用于TWS耳機，智能門鎖，安防監(jiān)控等市場
GENERAL DESCRIPTION
The XB6166ISA product is a high
integration solution for lithium
ion/polymer battery protection.
XB6166ISA contains advanced power
MOSFET, high-accuracy voltage
detection circuits and delay circuits.
XB6166ISA 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.
XB6166ISA 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 long
term battery life.
