DATASHEET ISL9301 High Input Voltage Charger With Power Path Management FN6435 Rev 3.00 September 21, 2011 The ISL9301 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 accepts an input voltage up to 28V but is disabled when the input voltage exceeds 10.5V OVP threshold. The 28V rating eliminates the overvoltage protection circuit required in a low-voltage charger. The charge current and the end-of-charge (EOC) current are programmable with external resistors. When the battery voltage is lower than 2.8V, the charger preconditions the battery with 16% of the programmed charge current.
