  1. Hi, A full diagram would have been more helpful to understand the circuit, with your provided circuit its hard to tell. You need to specify at the very least the other pins 16 and 3 of the TL494. However from the point of connection alone - trimpot touching the 0.1 ohm sense resistors - it looks like current limit control where the trimpot is controlling the current and the MCU setting the high side with GPIO - much like an enable signal. Again without further details I can't tell for sure. Good luck with your studies
