TO263-7L

• Under voltage shut down

• Driver circuit with logic level inputs

• Typical slew rate of 1 V/µs with open SR pin

• Adjustable slew rates for optimized EMI

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 ꢀꢁꢂ 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.
