Description
- Measuring Current in i.MX Applications Case Study based on INA250A4 Sensor Board. The sensor board connects to the target board via JP1. Polarity is important in order for the INA250A4 output to measure the current properly. FET Q1 is used to short the pins of JP1, allowing the INA250A4 to be taken out of the measurement loop. FET Q2 is used to take one leg of the INA250A4 out of the measurement loop so that calibration of the sensor may be performed immediately before making a measurement to minimize temperature effects on the sensor
