One Cell Lithium-ion/Polymer Battery Protection IC
The XB9301A product is a high
integration solution for lithium-
ion/polymer battery protection.
XB9301A contains advanced power
MOSFET, high-accuracy voltage
detection circuits and delay circuits.
XB9301A is put into an ultra-small
DFN3.5X2.5X0.55-6 package and only
one external component makes it an
ideal solution in limited space of battery
XB9301A 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.
