It may be, is it INA231 based on Breakout board demos topic?
Re:load is using an op amp as a voltage buffer/comparator circuit to control the MOSFET. It doesn’t have a closed loop control method, I was planning on using the other op amp in the same package to amplify the voltage drop on the resistor and monitor things with an ADC pin, so I would’ve used 2 pins only: one for PWM signal, another for ADC. But with INA231, we can use it for measuring supply voltage as well. There’s an alert pin, automatic power calculation… It’s definitely something to consider.
