Product Summary
The ISL6294 is a cost-effective, fully integrated high inputvoltage single-cell Li-ion battery charger. The charger uses aCC/CV charge profile required by Li-ion batteries. Thecharger accepts an input voltage up to 28V but is disabledwhen the input voltage exceeds the OVP threshold, typically6.8V, to prevent excessive power dissipation. The 28V ratingeliminates the overvoltage protection circuit required in a lowinput voltage charger.
