Excuse me, current detection: What is the difference between high-end detection and low-end detection? What are the disadvantages? What should I pay attention to?

Generally speaking, the high side is that the sampling resistor is connected in series to the system power supply, and the impact on the system is to reduce the operating voltage, while the low side is that the sampling resistor is connected in series between the system ground and the entire GND of the PCB, which raises the GND of the system. Reference point.

Which one is better depends on the specific system application and requirements. High side has higher requirements for the components of the acquisition and detection system.

High-end detection is not easy to implement on the circuit, or the circuit is complicated and the accuracy is low.

Generally, low-end detection is used.
