Maxim ±15kV ESD保护USB收发器MAX3450E/MAX3451E/MAX3452E为低电压ASIC/CPU提供了一种USB兼容的物理层接口方案,USB的D+和D-数据线可承受±15kV人体放电模式的冲击。MAX3451E包括1.5kΩ的上拉电阻和计数输入;MAX3452E能够检测有效的VBUS,为ASIC/CPU提供相应的逻辑指示输出。
Maxim’s ± 15kV ESD-Protected USB Transceivers The MAX3450E / MAX3451E / MAX3452E provide a USB-compatible physical layer interface solution for low-voltage ASICs / CPUs that can withstand ± 15kV human body discharge modes with USB D + and D- data lines. The MAX3451E includes a 1.5kΩ pullup resistor and count input. The MAX3452E can detect a valid VBUS and provide a corresponding logic indication output for the ASIC / CPU.
