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.
