ISL9222, High Input Voltage Charger

ISL9222 High Input Voltage Charger The ISL9222 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 6.8V, to prevent excessive power dissipation.

The 28V rating eliminates the overvoltage protection circuit required in a low input voltage charger.
