SSC5918
One Cell Lithium-ion/Polymer Battery Protection IC
Features
General Description
Reduction in Board Size due to Miniature Package
SOT-23-6.
Ultra-Low Quiescent Current at 3μA (Vcc=3.9V).
Auto recovery
0v charging
Precision Overcharge Protection Voltage
4.375V ±25mV and 4.425V ±25mV
Load Detection Function during Overcharge Mode.
Two Detection Levels for Overcurrent Protection.
Delay times are generated by internal circuits. No
external capacitors required.
Pin Configuration
SOT23-6
TOP VIEW
The SSC5918 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 SSC5918 into
the limited space of battery pack. The accurate ±25mV
overcharging detection voltage ensures safe and full
utilization charging. The very low standby current drains
little current from the cell while in storage.
Applications
