It’s part of [JM’s] post about the in’s and out’s of building microcontroller friendly motor controllers (translated). This particular setup is a half H-bridge ... can be a big problem.

you are likely to reach for an L298N to interface your microcontroller to the motor, probably in an H-bridge configuration. [Dronebot] has used L298N chips like this many times. In the video below ...

An intelligent full-bridge drive with integrated protections and a dedicated output-status pin simplifies designs of low/mid-power DC-motor systems. The motor driver integrates the high- and low ...
