ISL6298规格书详情
描述 Description
The ISL6298 is an integrated single-cell Li-ion or Li-polymer battery charger optimized for low current applications. The targeted applications include mini-disk (MD) players, Bluetooth® headsets, or other applications that use low-capacity battery cells. The ISL6298 is a linear charger that charges the battery in a CC/CV (constant current/constant voltage) profile. The charge current is programmable with an external resistor up to 450mA during the CC phase. Once the battery voltage reaches 4.2V (or 4.1V), the charger enters CV mode and the charge current starts to reduce. When the charger current drops to a user-programmable threshold, the charger indicates the end-of-charge with a STATUS pin. The charger does not actually terminate until a user-programmable total fast charge time is reached. If the battery voltage drops to a recharge threshold after termination, the charger will recharge the battery to its full capacity. The charger preconditions the battery with 20% of the programmed CC current if the battery voltage is below 2.8V. The total precharge time is limited to 1/8 of the total fast charge time. The ISL6298 features charge current thermal foldback to guarantee safe operation when the printed circuit board is space-limited for thermal dissipation. Additional features include an NTC thermistor interface for monitoring the ambient temperature, the ability to disable the time limit of the fast charge, an FAULT indication, and a thermally enhanced QFN or DFN package.
