INTERSIL ISL9204 High Input Voltage Charger handbook
Update: 30 September, 2023
ISL9204 is a high input voltage single-cell Li-ion battery charger from Intersil. This charger can accept up to 28V input voltage, but is disabled when the input voltage exceeds the OVP threshold (minimum 10V) to prevent excessive power dissipation. The 28V rating eliminates the overvoltage protection circuit required in a low input voltage charger. The charge current and the end-of-charge (EOC) current are programmable with external resistors. When the battery voltage is lower than a typical value of 2.8V, the charger preconditions the battery with typically 17% of the programmed charge current. When the charge current reduces to the programmable EOC current level during the CV charge phase, an EOC indication is provided by the CHG pin, which is an open-drain output. An internal thermal foldback function protects the charger from any thermal failure. Two indication pins (PPR and CHG) allow simple interface to a microprocessor or LEDs. When no adapter is attached or when disabled, the charger will enter a low power mode until a battery is connected or the charger is enabled.
