        GENERAL DESCRIPTION

        The HP2602 is a charger front-end integrated circuit
        designed to provide protection to Li-ion batteries from
        abnormal conditions. The device monitors the input voltage
        and the charging current to make sure both parameters are
        in normal range. The device will switch off internal MOSFET
        to disconnect IN from OUT to protect load when any of input
        voltage or output current exceeds the threshold. The Over
        Temperature Protection (OTP) function monitors chip
        temperature to protect the device. The device operates like
        a linear regulator, maintaining a 5.45V output with wide
        input voltage range.
        The HP2602 is available in DFN-2x2-8L, DFN-2x2-6L and
        SOT23-5L package. Standard products are Pb-free and
        Halogen-free.
