Four ways to control automotive solenoids/actuators using power MOSFETs

Показать описание
Automotive solenoids or actuators have four main control operations. Each different topology has its pros and cons, and it is important to understand these options when choosing a specific design.

Join Richard in this video as he talks through the characteristics and trade offs to consider with each topology.

I wondered about the 'more energy efficiency' of the boost design...it looks like inductive transient energy can be recycled into the boost circuit, but this was not explicitly explained here... if I'm right, it might be useful to add something about that into this, or another, talk?
How important is the SOA of the FET in the active clamp...it seems to be of limited importance, since the device does not spend much time (hopefully ;-) ) in a 'pinch' state that is the worst-case SOA issue?
