DESCRIPTION:
The MSK 4354 is a 10 Amp, 3 Phase Bridge Smart Power Motor Drive Hybrid with a 600 volt rating on the output switches. The output switches are Insulated Gate Bipolar Transistors (IGBT's). The free-wheeling diodes are Fast Recovery Epitaxial Diodes (FRED's) to provide matched current capabilities with the IGBT's and are specified with excellent reverse recovery times. This new smart power motor drive hybrid is 5.0 volt input logic compatible. Under-voltage lockout shuts down the bridge when the supply voltage gets to a point of incomplete turn-on of the output switches. The internal high-side bootstrap power supply derived from the +VB supply completely eliminates the need for 3 floating independent power supplies.

APPLICATION NOTES MSK 4354 PIN DESCRIPTIONS
+VCC - Is the low voltage supply for all the internal logic and drivers. A 0.1 F ceramic capacitor in parallel with a 10F tantalum capacitor is the recommended bypassing from the +VCC pin to the COM pin. H INA, H INB, H INC - Are high active logic inputs for signalling the corresponding phase high-side switch to turn on. The logic inputs are compatible with standard CMOS or LSTTL outputs. These logic inputs are internally zener clamped at 5.2 volts. L INA, L INB, L INC - Are low active logic inputs for signalling the corresponding phase low-side switch to turn on. The logic inputs are compatible with standard CMOS or LSTTL outputs. These logic numbers are internally zener clamped at 5.2 volts. AO, BO, CO - Are the pins connecting the 3 phase bridge switch options. AV-, BV-, CV- - Are the connections from the bottoms of the three half bridges. These pins get connected to the COM pin. If current sensing is desired they may be connected to the COM pin through a low value sense resistor. +VB - Is the connection used to provide power to the floating high-side bootstrap supplies in the gate drive circuitry. V+ - Is the high voltage positive rail connection to the tops of the three half bridges. Proper power supply bypassing must be connected from this pin to the COM pin for good filtering. This bypassing must be done as close to the hybrid as possible. COM - Is the connection that all hybrid power supply connections are returned to and bypassed to.

TYPICAL SYSTEM OPERATION
The MSK 4354 is designed to be used with a +270 volt high voltage bus, +15 volt low power bus and +5 volt logic signals. Proper derating should be applied when designing the MSK 4354 into a system. High frequency layout techniques with ground planes on a printed circuit board is the only method that should be used for circuit construction. This will prevent pulse jitter caused by excessive noise pickup on the current sense signal or the error amp signal. Ground planes for the lower power circuitry and the high power circuitry should be kept separate. The connection between the bottom of the current sense resistor, COM pin and the high power ground, AV-, BV- and CV- pins are connected at this point. This is a critical path and high currents should not be flowing between the current sense and COM. Inductance in this path should be kept to a minimum. An RC filter (shown in 2 places) will filter out the current spikes and keep the detected noise for those circuits down to a minimum. In the system shown a PWM pulse by pulse current limit scheme controlled by the motor controller is implemented. When controlling the motor speed by the PWM method, it is required that the low side switches be PWM pulsed due to the bootstrap supplies used to power the high side switch drives. The higher the PWM speed the higher the current load on the drive supply. PWM of the low side will prevent sagging of the high side supplies. A separate pin (+VB) is provided for connecting an external floating power supply to power the bootstrap supplies.
