Functional Pin Description VIN (Pin 1, 15, 16) VIN is the input power source pin that is connected to a wall adapter. FAULT (Pin 2) FAULT is an open-drain output indicating fault status. When a fault condition occurs, this pin ...

... It is not recommended to fast charge a Li-ion battery when the battery is deeply discharged, indicated by a low battery voltage. When the ISL6291 sees a battery voltage lower than the V Specifications, it forces 1/10 of the current in the constant current mode into the battery ...

... During the constant current charge mode, the STATUS pin remains LOW and the FAULT pin remains HIGH. Constant Voltage Charge Mode The ISL6291 regulates the battery terminal voltage at V the constant voltage mode. As the battery continues being charged, the charge current starts to decrease, as shown in Figure 1 ...

... C Battery Pack Temperature Monitoring The ISL6291 uses two comparators to form a window comparator. Figure 3 shows the internal circuit. When the TEMP pin voltage is “out of the window,” as determined by the V and V , the charging is stopped. The two ...

... The ISL6291 assumes that the thermistor is co-packed with the battery and is removed together with the battery. When the ISL6291 sees a voltage of 2.1V or higher on the TEMP pin, it assumes that the battery is removed. When the battery is removed, the charger stops and indicates a fault signal. A new charge cycle starts when a battery is inserted again ...
