Hello,
I'm trying to reverse engineer an electronic board that controls a brush motor.
I came up with this schematic after working with the board for a while.
The U2 mosfet controls the pump (motor) using typical Source Follower.
But the U1 mosfet, I don't know what function it has in this circuit, I don't understand its operation in this circuit.
Could any of you help me understand this circuit.
Thank you so much
