... The battery is charged in a CC/CV (constant current/constant voltage) profile. The charge current is programmable with an external resistor up to 2A. The ISL6292 can also work with a current-limited adapter to minimize the thermal dissipation, in which case, the ISL6292 combines the benefits of both a linear charger and a pulse charger ...

... ISL6292 The charger automatically re-charges the battery when the battery voltage drops below a recharge threshold. When the wall adapter is not present, the ISL6292 draws less than 1 current from the battery. Three indication pins are available from the charger to indicate the charge status. The V2P8 outputs a 2.8VDC ...

... The two indication pins, STATUS and FAULT, indicate a LOW and a HIGH logic signal respectively. Figure 19 illustrates the start-up of the charger between t The ISL6292 has a typical rising POR threshold of 3.4V and a falling POR threshold of 2.4V. The 2.4V falling threshold guarantees charger operation with a current-limited adapter to minimize the thermal dissipation ...

... Shutdown The ISL6292 can be shutdown by pulling the EN pin to ground. When shut down, the charger draws typically less than 30µA current from the input power and the 2.8V output at the V2P8 pin is also turned off. The EN pin needs to be driven with an open-drain or open-collector logic output, so (EQ ...

... As the charge current drops, the adapter output moves from point B to point C, shown in Figure 24. The battery pack can be approximated as an ideal cell with a lumped-sum resistance in series, also shown in Figure 24. The ISL6292 charger sits between the adapter and the battery ...
