ISO-9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. FEATURES: 25 AMP, 500 VOLT IGBT PLUS DIODE FULLY ISOLATED SMART POWER 3-PHASE MOTOR DRIVE POWER HYBRID 4358 (315) 701-6751 4707 Dey Road Liverpool, N.Y. 13088 500V, 25 Amp Capability at 110°C Fully Isolated Bridge Ultra Low Thermal Resistance Integral Free Wheeling Fast Recovery Epitaxial Diode (FRED) Self-Contained, Smart Lowside/Highside Drive Circuitry and Isolated Supply Adjustable Deadtime Capable of Switching Frequencies to 20KHz Isolated Case Allows Direct Heat Sinking Case Bolt-down Design Allows Superior Heat Dissipation MIL-PRF-38534 CERTIFIED DESCRIPTION: The MSK 4358 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 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 s...
