... The two indication pins, STATUS and FAULT, indicate a LOW and a HIGH logic signal respectively. Figure 20 illustrates the startup of the charger between t The ISL6298 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 ...

... Fault *Both outputs are pulled up with external resistors. Shutdown The ISL6298 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 less than 3µA current from the battery. The 2.8V output at the V2P8 pin is also turned off ...
