... Data Sheet High Input Voltage Charger The ISL6294 is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger. The charger uses a CC/CV charge profile required by Li-ion batteries. The charger accepts an input voltage up to 28V but is disabled when the input voltage exceeds the OVP threshold, typically 6 ...

... I REF 2.55V 19%I REF CHG Description The ISL6294 charges a Li-ion battery using a CC/CV profile. The constant current I is set with the external resistor REF R (See Figure 1) and the constant voltage is fixed at IREF 4.2V. If the battery voltage is below a typical 2.55V trickle- charge threshold, the ISL6294 charges the battery with a ...
