Power Stage Characteristics
The power stages of the FAN7093 consist of a P-channel vertical DMOS transistor for the high-side switch and an 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 2 , allowing active freewheeling and minimizing power
dissipation in the forward operation of the integrated diodes.
The on-state resistance, R DS(ON) , is dependent on the supply voltage V BATT as well as on the junction temperature, T J .

Specified R DS(ON) value is related to normal soldering points; R DS(ON) values are specified for
FAN7093_F085: pin 1,7 to pin 8 (tab, backside).
Due to active freewheeling, the diode is conducting only for a few μs, depending on the value of the
external R SR resistor.

The minimum duty cycle is 34% when V BATT =14 V, R SR is shorted and the following parameters are at their typical values:
t d(ON)HS , t d(ON)LS , t Slew(on)HS , and t Slew(on)LS.
