Theory of Operation The ISL6292D is an integrated charger for single-cell Li-ion or Li-polymer batteries. The ISL6292D functions as a traditional linear charger when powered with a voltage- source adapter. When powered with a current-limited adapter, the charger minimizes the ...

I is the charge current. The maximum power CHARGE dissipation occurs during the beginning of the CC mode. The maximum power the IC is capable of dissipating is dependent on the thermal impedance of the printed-circuit board (PCB). Figure ...

The following events initiate a new charge cycle: • POR, • a new battery being inserted (detected by TEMP pin), • the battery voltage drops below a recharge threshold after completing a charge cycle, • recovery from an battery over-temperature ...

End-of-Charge (EOC) Current The end-of-charge current I sets the level at which the MIN charger indicates the end of the charge with the STAT1 and STAT2 pins, as shown in Figure 4. The charger terminates at this moment. The I ...

As the TEMP pin voltage rises from low and exceeds the 1.5V threshold (when the V2P8 pin is forced with a 3V bias), the under temperature signal rises and does not clear until the TEMP pin voltage falls below the ...

... The ISL6292D can work with a current-limited adapter to significantly reduce the thermal dissipation during charging. Refer to the ISL6292 datasheet, which can be found at http://www.intersil.com, for more details. Board Layout Recommendations The ISL6292D internal thermal foldback function limits the charge current when the internal temperature reaches approximately 100° ...
