Webwhile the first-stage voltage Op Amps and current-sense INA are used to measure battery voltage and charging current of the battery cell or battery pack. The switch between the current-sense Op Amp and the sense resistor s that the input to the current-sense Op Amp is positive regardless of the direction of current flow across the sense resistor. WebIntroduction. It can be challenging to sense currents exceeding 50 A because the task often involves thermal management, must take place in a limited PCB area, and in some cases, requires a voltage isolation device. Two widely used methods for sensing high currents are a sense-resistor/op-amp approach, and Hall-based current sensing.
