ISL9204 High Input Voltage Charger

ISL9204 High Input Voltage Charger The ISL9204 is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger. This 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, minimum 10V, to prevent exce.
