The ISL9222A 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 7.
2V, to prevent excessive power dissipation.
The 28V rating eliminates the over
voltage protection circuit required in a low input
voltage charger.
The charge current is user programmable with an ext...
