General Description

The FS326E+G battery protection IC is designed to

protect lithium-ion/polymer battery from damage or

degrading the lifetime due to overcharge,

overdischarge, and/or overcurrent for one-cell

lithium-ion/polymer battery powered systems, such

as cellular phones.

The ultra-small package and less required external

components make it ideal to integrate the

FS326E+G into the limited space of battery pack.

The accurate ±40mV overcharging detection voltage

ensures safe and full utilization charging. The very

low standby current drains little current from the cell

while in storage.

Features



Reduction in Board Size due to Miniature

Package SOT-23-6.



Ultra-Low Quiescent Current at 3μ A (Vcc=3.9V).



Ultra-Low Overdischarge Current at 3 μ A

(Vcc=2.0V).



Precision Overcharge Protection Voltage 4.3V ±

40mV



Load Detection Function during Overcharge

Mode.



Two Detection Levels for Overcurrent Protection.



Delay times are generated by internal circuits. No

external capacitors required.
