GENERAL DESCRIPTION
The XB6090 SERIES product is a high
integration solution for lithium
ion/polymer battery protection. XB6090
SERIES contains advanced power
MOSFET, high-accuracy voltage
detection circuits and delay circuits.
XB6090 SERIES is put into an
DFN1X1x0.37-4 package and only one
external component makes it an ideal
solution in limited space of battery pack.
XB6090 SERIES 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.
