| ISO 9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. FEATURES: 10 AMP, 75V, 3 PHASE MOSFET BRIDGE WITH INTELLIGENT INTEGRATED GATE DRIVE 4400 (315) 701-6751 4707 Dey Road Liverpool, M/Y. 13088 75 Volt Motor Supply Voltage 10 Amp Output Switch Capability, All N-Channel MOSFET Output Bridge 100% Duty Cycle High Side Conduction Capable Suitable for PWM Applications from DC to 100KHz Shoot-Through/Cross Conduction Protection Undervoltage Lockout Protection Programmable Dead-Time Control Low Active Enable for Bridge Shutdown Control Isolated Base Plate Design for High Voltage Isolation Plus Good Thermal Transfer 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.

The wiring to these pins should be sized according to the required current by the motor. There are no short circuit provisions for these outputs. 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 current 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 output 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. 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. 1000F 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 current in the bridge. Both pins must be connected. If a resistor is not used, these pins must be connected to GND. 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 between 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 bypassed to GND using a 0.1F ceramic capacitor and a 4.7F bulk capacitor. 3 Rev.
