ISL9230 High Power Li-Ion Charger W/I-Path Management The ISL9230 is a fully integrated high input voltage single-cell Li-ion battery charger with power path management function.

This charger performs the CC/CV charge function required by Li-ion batteries.

The charger can withstand an input voltage up to 26V but is disabled when the input voltage exceeds 6.6V OVP threshold.

The input current limit and charge current are programmable with external resistors.

When the battery voltage is lower than
