ZHCSC46C February 2014 – June 2021 INA300
With the input terminals of a second INA300 device reversed across the same current-sensing resistor, the second INA300 device is now able to detect current flowing in the other direction relative to the first device, as shown in Figure 8-3. The outputs of each INA300 device connect to an AND gate to detect if either of the limit threshold levels are exceeded. The output of the AND gate is high if neither overcurrent limit thresholds are exceeded. A low output state of the AND gate indicates that either the positive overcurrent limit or the negative overcurrent limit are surpassed.
