General Description
The TS2208A/B series are over-charge/discharge protection ICs for rechargeable one-cell Lithium-ion batteries. They bear an over-charge/over-discharge threshold for the battery cell voltage during charging/discharging process, and also provide on-time protection when excess current or short circuit occurs.
FEATUREs

Supply current 3uA (typ) and standby current 0.1uA
✧ High withstand voltage up to 22V (VDD ~ V-)
✧ High accuracy voltage detection
✧ Over charge detector
✧ Over discharge detector
✧ Over current and short circuit protection
✧ Small package of SOT-26
APPLICATIONs
✧ Over-charge and over-discharge protection for Li-ion
cell pack
✧ High precision protectors for cell-phones and other
gadget using on board Li-ion cell battery
