Working Principle of ISL6292BCRZ

The ISL6292BCRZ is a switching-mode battery charger intended to be used with lithium-based battery technology such as Li-Ion and Li-Cobalt. The battery charger utilizes a valley switching power converter to convert power from an A/C adapter or a USB port to charge a battery. This converter switches at a fixed frequency to achieve the highest efficiency while providing a regulated output voltage of 4.2V.

The ISL6292BCRZ contains a DC voltage regulator, charging logic and output power control circuit. The rechargeable battery is connected in series to the DC voltage regulator. When an adapter is connected to the DC-input, the battery charger will enter the charging mode. During this mode, the battery charger continuously monitors the charge current and regulates its output voltage to maintain the proper battery voltage level.

The ISL6292BCRZ supports multiple charge currents, from 0.1A up to 2A, ensuring both fast and safe charging. The fast charging mode is intended to quickly charge the battery in a short period of time to a certain capacity. Meanwhile, the safety charging mode is implemented to protect the battery from deep discharge damage. The ISL6292BCRZ also provides several safety features that protect the battery and device against over-charging, short-circuit, over-voltage, over temperature, and charge status.

In summary, the ISL6292BCRZ is a versatile switching-mode battery charger that is suitable for a range of portable consumer electronic and industrial applications. It is capable of providing multiple charging currents from 0.1A to 2A, ensuring both fast and safe charging of the target battery.
