® ISL9219 Data Sheet April 7, 2010 FN6606.2 Li-ion Battery Charger The ISL9219 is a fully integrated high input voltage single-cell Li-ion battery charger. This charger is fully in compliance with the USB electrical specification. The charger performs the CC/CV charge function 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 6V, to prevent excessive power dissipation. The 28V rating eliminates the overvoltage protection circuit required in a low input voltage charger. The fast charge current is programmable with an external resistor, and the end-of-charge (EOC) current is fixed at 50mA for any input source type.
