DESCRIPTION:
The MSK4358 is a 25 Amp, 3 Phase Isolated 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
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. The bridge is optically isolated from the control circuitry. This new
smart power motor drive hybrid is compatible with 5V CMOS logic levels. The internal circuitry prevents simultaneous
turn-on of the in-line half bridge transistors with adjustable 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 isolated 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 MSK4358 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 MSK4358 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 two sections of the hybrid are completely
isolated, and can float relative to each other without referencing one to the other. An RC filter will filter out the current spikes and keep the
detected noise for that circuit down to a minimum.
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 MSK4358 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 high side controller output.
