2 Brief functional Description
The FAN7093_F085 is an integrated high current half bridge for
electric motor drive applications. It contains one P-channel high-
side MOSFET and one N-channel low-side MOSFET with an
integrated control IC in one package. With the P-channel high-
side switch the need for a charge pump is eliminated and
therefore minimizing EMI. Pins IN and  are logic level inputs
and control the half bridge outputs. The diagnostic current output
pin IS outputs a proportional current through the half bridge
MOSFETS. The IS pin output represents current for either the P-
Chan or the N-Chan depending on which is active. The part is
protected against short to Battery or ground, over current, over-
temperature, over voltage and under voltage. The
FAN7093_F085 provides a cost optimized solution for protected
high current PWM motor drives with very low board space
consumption.
