7 Power Stages
The power stages of the FAN7093_F085 consist of a p-channel vertical DMOS transistor for the high
side switch and a n-channel vertical DMOS transistor for the low side switch. All protection and
diagnostic functions are located in the control die. Both switches can be operated up to 60 kHz,
allowing active freewheeling and thus minimizing power dissipation in the forward operation of the
