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.
