Renesas Electronics Corporation High Power Li-Ion Charger W/I-Path Management ISL9230IRZ

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 3.0V, the charger preconditions the battery with 10% of the programmed charge current. When the charge current reduces to the end-of-charge (EOC) current level during the CV charge phase, the EOC indicator (span style="text-decoration: overline"CHG/span) will toggle to a logic high to indicate the end-of-charge condition.brbr The ISL9230 uses separate power paths to supply the system load and the battery. This feature allows the system to immediately operate with a completely discharged battery. This feature also allows the charge to terminate when the battery is full while continuing to supply the system power from the input source, thus minimizing unnecessary charge/discharge cycles and prolonging the battery life.brbr Two indication pins (span style="text-decoration: overline"PG/span and span style="text-decoration: overline"CHG/span) allow simple interface to a microprocessor or LEDs.
