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.

The TS2208A/B series are essentially composed of a reference unit and three voltage detectors. During charging

process, when the cell voltage/V_DDcrosses the over-charge threshold voltage V_C1, the over charge detector (COM1) will

switch the output pin (C_OUT) to a low level within a delay time (t_C1), and thus turning off the MOSFET connected to the

charging path. The C_OUTpin may change to high level again when the V_DDvoltage falls below “V_C1-V_HYS”, or when V_DD

falls below V_C1while the charger is disconnected from the battery pack.

During the discharging process, when the V_DDvoltage crosses the over-discharge threshold voltage (V_D1), the

over-discharge detector (COM2) will switch D_OUTto low level within a delay time (t_D1), and thus turning off the MOSFET

connecting the discharging path. In the mean time, the TS2208A/B series will enter a low current standby mode. Once

into standby mode, it can only be released from standby after the battery pack is connected to a charger.

The conditions of excess current and short circuit protection are both determined according to the voltage at the V- pin.

As the voltage of V- pin reaches a greater value than V_OC, which means an undesirable large current is flowing through

the path, D_OUTwill be switched to a low level and the path is cutoff after internally pre-set delay time (t_OC) elapses. In the

case of short circuit, i.e. V- rises above V_SHORT, the path will also be cutoff but with almost no delay time. Once the excess

current or short circuit fault is removed, the built-in resistor at the V- pin, typically 100kohm, will pull V- down to V_SSand

bringing the IC back to normal operation.

Together with the application circuit, the TS2208A/B will function as a consummate protector for Li-ion battery packs

which leads to safety and long lifetime.
