Driving Inductive loads with MOSFETs - NXP Quick Learning 44 (part 1)

, MOSFETs are used to control current flow to loads which are dominantly inductive (such as motors or solenoids). Some inductive energy is inevitably stored in the load inductance. It needs to be managed carefully when the load current is switched OFF by a MOSFET. This two-part quick learning series outlines real world scenarios where MOSFETs are used in this way, particularly where ‘freewheel’ diodes cannot be used to divert the current when the MOSFET is switched OFF. In these cases avalanche or active
