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, allowing active freewheeling and minimizing power
dissipation in the forward operation of the integrated diodes.
The on-state resistance, RDS(ON), is dependent on the supply voltage VBATT as well as on the junction temperature, TJ.

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