  • PW2606B.pdf規格書下載

    The PW2606B is a front-end over voltage and over current protection device. It achieves wide inputvoltage range from 2.5VDC to 40VDC. The over voltage threshold can be programmed externally orset to internal default setting. The low resistance of integrated power path nFET switch ensures betterperformance for battery charging system applications. It can deliver up to 1A current to satisfy thebattery supply system. It integrates the over-temperature protection shutdown and auto-recoverycircuit with hysteresis to protect against over current events

  • PW2601_2.0.pdf規格書下載

    The PW2601 is a charger front-end integrated circuit designed to provide protection to Li-ionbatteries from failures of charging circuitry. The device monitors the input voltage, battery voltageand the charging current to make sure all three parameters are operated in normal range. Thedevice will switch off internal MOSFET to disconnect IN to OUT to protect load when any of inputvoltage, output current exceeds the threshold. The Over temperature protection (OTP) functionmonitors chip temperature to protect the device. The PW2601 also can protect the system’sbattery from being over charged by monitors the battery voltage continuously. The deviceoperates 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
