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 over- voltage threshold. PW2601是一款充電器前端集成電路,旨在為鋰離子電池提供保護,使其免受充電電路故障的影響。該設備監視輸入電壓,電池電壓和充電電流,以確保所有三個參數均在正常范圍內運行。當任何輸入電壓,輸出電流超過閾值時,該器件將關閉內部MOSFET以斷開IN至OUT的連接,以保護負載。過熱保護(OTP)功能監視芯片溫度以保護器件。 PW2601還可以通過連續監視電池電壓來保護系統電池免于過充電。該器件的工作原理類似于線性穩壓器,可在輸入電壓高達輸入過壓閾值的情況下保持5.1V輸出。 The PW2601 is available in DFN-2x2-8L package. Standard products are Pb-free and Halogen- free. PW2601采用DFN-2x2-8L封裝。標準產品是無鉛和無鹵素的。 FEATURES特征 Maximum Input Voltage: 24V最大輸入電壓:24V Programmable OCP: Up to 1.5A可編程OCP:高達1.5A Input OVP: 6.8V輸入OVP:6.8V OVP Response Time: Less Than 1usOVP響應時間:少于1us Battery OVP threshold: 4.35V (Typ.)電池OVP閾值:4.35V(Typ。) Over Temperature Protection過溫保護 Soft-Start to Prevent Inrush Currents軟啟動,防止涌入電流 TYPICAL APPLICATION CIRCUIT典型電路 |
