One Cell Lithium-ion/Polymer Battery Protection IC
GENERAL DESCRIPTION
The XB4301 series product is a high
integration solution for lithium-
FEATURES
Protection of Battery Cell Reverse
Connection
Integrate Advanced Power MOSFET
withEquivalent of 54m RDS(ON)
ion/polymer battery protection. XB4301
contains advanced power MOSFET,
high-accuracy voltage detection circuits
and delay circuits. XB4301 is put into an
ultra-small SOT23-5 package and only
one external component makes it an
ideal solution in limited space of battery
pack.
XB4301 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.
