App note from Nexperia about various solenoid driver used in automotive. Link here (PDF) There are a wide variety of solenoid drive circuit topologies. Most of them use MOSFETs in various configurations and driving modes. In this application note four of them will be discussed: solenoid driver with free-wheeling diode, solenoid driver with MOSFET avalanching, […]

Solenoid control project
Doub shared his solenoid control project in the forum: I’m working on a solenoid control board, that would allow me to do sensorless position control (the algorithm is based on the varying inductance of the solenoid depending on the plunger position).
