DESCRIPTION:
The MSK 4357 is a 28 Amp, 3 Phase Bridge Smart Power Motor Drive Hybrid with a 500 volt rating. The output
switches are Insulated Gate Bipolar Transistors (IGBT's) tailored for high switching speeds. The free-wheeling diodes
are the new Fast Recovery Epitaxial Diodes (FRED's) to provide matched current capabilities with the IGBT's and are
specified with excellent reverse recovery times at high current ratings. This new smart power motor drive hybrid is
compatible with 5V CMOS or TTL logic levels. The internal circuitry prevents simultaneous turn-on of the in-line half
bridge transistors with a built-in 2uS deadtime to prevent shoot-through. Undervoltage 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 power
supply derived from the +15 volt supply completely eliminates the need for 3 floating independent power supplies for
the high-side drive.

TYPICAL SYSTEM OPERATION
The MSK4357 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 MSK4357 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 low power circuitry and high power circuitry should be kept separate. The connection between the bottom
of the current sense resistor, VSS pin and the high power ground are connected at this point. This is a critical path, and high
currents should not be flowing between the current sense and VSS. 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, two types of current limit are implemented. The first limit is a PWM pulse by pulse limit controlled by the
motor controller. A second absolute maximum limit is set up for the MSK4357 which will completely shut off the bridge in the
event that current limit is exceeded.
The logic signals coming from the typical motor controller IC are set up for driving N channel low side and P channel high side
switches directly, and are usually 15 volt levels. Provision should be made for getting 5 volt logic signals to the MSK4357 of the
correct assertion levels. Typically, the low side signals out of the controller are high active and the high side are low active.
Inverters are shown in the system schematic for the low side controller output.
