The invention belongs to the technical field of suspension controllers, and relates to a bridge type field effect transistor driving circuit and an electromagnetic coil controller. The bridge type field effect transistor driving circuit comprises a level conversion isolation module, a first field effect transistor circuit, a second field effect transistor circuit and a driving chip. The driving chip is electrically connected with the first field effect transistor circuit and the second field effect transistor circuit; the first field effect transistor circuit and the second field effect transistor circuit are connected to form a bridge type reversible chopper circuit; and the input end of the level conversion isolation module is used for connecting the control module, and the output end is used for connecting the driving chip and isolating the control signal output by the control module from the bridge type reversible chopper circuit. According to the invention, the time length of turn-on and turn-off can be reduced, and the power loss of turn-on can be reduced to a certain extent.
