DESCRIPTION:
The MSK 4400 is a 3 phase MOSFET bridge plus drivers in a convenient isolated baseplate package. The
module is capable of 10 amps of output current and 75 volts of DC bus voltage. It has a full line of protection features,
including undervoltage lockout protection of the bias voltage, cross conduction control and a user programmable dead-time
control for shoot-through elimination. In addition, the bridge may be shut down by using the ENABLE control. The MSK
4400 provides good thermal conductivity for the MOSFETs due to an isolated plate design that allows direct heat sinking of
the device without insulators.

APPLICATION NOTES
MSK 4400 PINOUT DESCRIPTIONS
AØ, BØ, CØ - Are the connections to the motor phase
windings from the bridge output. The wiring to these pins
should be sized according to the required current by the
motor. There are no short circuit provisions for these out-
puts. Shorts to V+ or gound from these pins must be
avoided or the bridge will be destroyed.
AL, BL, CL - Are the logic level inputs for controlling the
low side switch for each of the three phases. A logic
HIGH turns the low side output on, sinking the output cur-
rent and pulling it down. If the corresponding high side
switch is ON, the device will turn off the high side output,
insert the dead time and then command the lowside out-
put on. The low side input has priority over the high side
input.
AH, BH, CH - Are the logic level inputs for controlling the
high side switch for each of the three phases. A logic low
turns the high side output ON, sourcing the output current
and pulling it up. If the corresponding low side switch is
ON, the device will ignore the high side input until the
lowside is turned off and dead time has elapsed. Again,
the lowside input has priority.
EN - Is the logic level input for enabling and disabling the
bridge outputs. A logic low enables output switching.
GND - Is the logic input return connection, the VBIAS
return and the V+ return.
SWR - Is the control for the amount of dead time be-
tween a high side switch ON and the corresponding low
side switch OFF and vice versa. Leaving it open creates
the most dead time, while connecting a 12 K resistor to
VBIAS creates the least.
VBIAS - Is the supply voltage for running all of the low
level logic and gate drive functions.This pin should be by-
passed to GND using a 0.1µF ceramic capacitor and a
4.7µF bulk capacitor.
AV+,BV+,CV+ - Are the power connections from the
hybrid to the bus. The pins for each phase are brought out
separately and must be connected together to the V+
source externally. The external wiring to these pins should
be sized according to the RMS current required by the
motor. These pins should be bypassed by a high quality
monolithic ceramic capacitor for high frequencies and
enough bulk capacitance for keeping the V+supply from
drooping. 1000µF of bulk capacitance was used in the
test circuit. The voltage range on these pins is from 16
volts up to 75 volts.
RSENSE - Is the connection point for the bottom of the
three phase bridge. A low value resistor between here
and the GND will produce a voltage proportional to cur-
rent in the bridge. Both pins must be connected. If a resis-
tor is not used, these pins must be connected to GND.
