DESCRIPTION:

The MSK 4351 is a 50 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 or TTL 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.
