MIL-PRF-38534 CERTIFIED 28 AMP, 500 VOLT IGBT PLUS DIODE SMART POWER 3-PHASE 4357M.S.KENNEDY CORP. MOTOR DRIVE HYBRID 4707 Dey Road Liverpool, N.Y. 13088 (315) 701-6751 FEATURES: 500V, 28 Amp Capability Ultra Low Thermal Resistance Integral Free Wheeling Fast Recovery Epitaxial Diode (FRED) Self-Contained, Smart Lowside/Highside Drive Circuitry Under-Voltage Lockout, Internal 2uS Deadtime Capable of Switching Frequencies to 25KHz Isolated Case Allows Direct Heat Sinking Case Bolt-down Design Allows Superior Heat Dissipation Contact MSK for MIL-PRF-38534 Qualification Status 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 ind...
