Description: 以MCS51单片机为例，采用寄生电源供电方式， P1 1口接单线总线为保证在有效的DS18B20时钟周期内提供足够的电流，可用一个MOSFET管和89C51的P1 0来完成对总线的上拉，当DS18B20处于写存储器操作和温度A/D变换操作时，总线上必须有强的上拉，上拉开启时间最大为10 μs。采用寄生电源供电方式是VDD和GND端均接地。-To MCS51 microcontroller, for example, using parasite power supply mode, P1 1 Kou take to ensure the single bus clock cycle in an effective DS18B20 to provide adequate current, can be a MOSFET, and the 89C51 of the P1 0 to complete the bus pull-up, When the DS18B20 write-memory operation and the temperature A/D conversion operation, the bus must have a strong pull, pull-open time up to 10 μs. Way of using parasite power supply VDD and the GND terminal are grounded.
