The PW2601 is a charger front-end integrated circuit designed to provide protection to Li-ion
batteries from failures of charging circuitry. The device monitors the input voltage, battery voltage
and the charging current to make sure all three parameters are operated in normal range. The
device will switch off internal MOSFET to disconnect IN to OUT to protect load when any of input
voltage, output current exceeds the threshold. The Over temperature protection (OTP) function
monitors chip temperature to protect the device. The PW2601 also can protect the system’s
battery from being over charged by monitors the battery voltage continuously. The device
operates like a linear regulator, maintaining a 5.1V output with input voltages up to the input overvoltage threshold.
The PW2601 is available in DFN-2x2-8L package. Standard products are Pb-free and Halogenfree
