STNS01中文资料具有LDO的锂离子线性电池充电器数据手册ST规格书

描述 Description

The STNS01 is a linear charger for single-cell Li-Ion batteries integrating an LDO regulator and several battery protection functions.

The STNS01 uses a CC/CV algorithm to charge the battery; the fast-charge current can be programmed using an external resistor. Pre-charge current and termination current are scaled accordingly. The floating voltage value is 4.2 V.

The input supply voltage is normally used to charge the battery and provide power to the LDO regulator. When a valid input voltage is not present and the battery is not empty, the device automatically switches to battery power.

The STNS01 integrates overcharge, over-discharge and overcurrent protection circuitry to prevent the battery from being damaged under fault conditions. It also features a charger enable input to stop the charging process when battery overtemperature is detected by an external circuitry.

When the shutdown mode is activated, the battery power consumption is reduced to less than 500 nA to maximize battery life during shelf time or shipping. The device is available in the DFN12L (3x3x0.75 mm) package.
