CXLD64122集成了一个功率晶体管以提供2A的最大输出电流的稳压电压，它还将电流限制、热关断和关断控制功能集成到一个芯片中。限流电路限制过载或短路条件下的最大输出电流。芯片上的热关机提供了保护，以防止过载的任何组合，从而产生过大的结温。CXLD64122的输出电压跟踪VREF引脚上的参考电压。通常使用一个连接到VREF引脚的电阻分压器为集成电路提供参考电压

产品概述 返回TOP
The CXLD64122 integrates a power transistor to provide regulated voltage with maximum output current of 2A. It also incorporates current-limit, thermal shutdown and shutdown control functions into a single chip. The current-limit circuit limits the maximum output current in overload or short-circuit conditions. The on-chip thermal shutdown provides protection against any combination of overload that would create excessive junction temperature. The output voltage of the CXLD64122 tracks the reference voltage on VREF pin. A resistor divider connected to VREF pin is usually used to provide reference voltage to the IC. In addition, an external ceramic capacitorand an open-drain transistor connected toVREF pin provides soft-start and shutdown control.Applying and holding a voltage below 0.35V (typ.) to VREF shuts off the output.
