过充电压4.3-4.475V可选，过放电压2.8V，过放电流0.95A，过充电流0.95A，持续放电电流0.5A，适用于TWS耳机，智能手表等产品
GENERAL DESCRIPTION
The XB4092 series product is a high
integration solution for lithium-
ion/polymer battery protection. XB4092
contains advanced power MOSFET,
high-accuracy voltage detection circuits
and delay circuits. XB4092 is put into an
ultra-small TSOT23-4 package and only
one external component makes it an
ideal solution in limited space of battery
pack.
XB4092 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.
