Description
The FAN7093 is an integrated high-current half-bridge
driver 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, which minimizes EMI.
Pins IN and /INH are logic-level inputs and control the
half-bridge output. The diagnostic and current sense IS
pin outputs a current that is proportional to the current
flowing through the half-bridge MOSFETs. The IS pin
output represents current for the P-channel or the N-
channel, depending on which is active.
The part is protected against a short to battery or
ground of the out pin, over-current, over-temperature,
over-voltage, and under-voltage conditions. The
FAN7093 provides a cost- and space-optimized solution
for protected high-current PWM motor drives.
