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.
