One Cell Lithium-ion/Polymer Battery Protection IC
The XB8688 series product is a high
integration solution for lithium-
ion/polymer battery protection. XB8688
contains advanced power MOSFET,
high-accuracy voltage detection circuits
and delay circuits. XB8688 is put into an
TSSOP8 package and only one external
component makes it an ideal solution in
limited space of battery pack.
XB8688 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 f or any other
Li-Ion and Li-Poly battery-powered
information appliances requiring long-
term battery life.
