hello everybody, i need some help on how to use fets
i need to design a driver for a bipolar stepper motor using fets, i'm using two h bridges of n-channel and p-channel fets and a l297 drive. i use it with 5v for the l297 and 12v for the motor. until now everything works fine, but the circuit is intended to work with 48v . thats where my problem starts, i'm using irf530 n-channel fets and irf9530 p-channel fets and in the data sheet says that the max vgs(gate-source V) is of +/-20v and if it surpases that the fet is destroyed. then.... my question is, how can i use it for those conditions without destroying the fet and aplying most at least 46V in the coils of the motor?
P.S.
i've already tried with zeners, they dont work
