I'm driving a DC motor (12 V, approx. 4 A) and I need to control the speed by PWM but I need one direction only and braking is not required.
My question is: is there any advantage to using a half-H bridge over using a simple low-side N-channel MOSFET (e.g. a IRLS3034-7PPbF)?
I'll be using a MOSFET driver (IXDN404 or similar) in order to switch fast enough and provide enough current to the gate and the PWM will be generated by an MCU.
