200V, 20 Amp Capability Self-Contained, Smart Lowside/Highside Drive Circuitry Under-Voltage Lockout, Internal 2S Deadtime Capable of Switching Frequencies to 25KHz Isolated Case Allows Direct Heat Sinking Case Bolt-down Design Allows Superior Heat Dissipation
DESCRIPTION:
The MSK 4422 is a 20 Amp, 3 Phase Bridge Smart Power Motor Drive Hybrid with a 200 volt rating on the output switches. The output switches are power MOSFETs with intrinsic fast-recovery diodes for the freewheeling currents of motor drives. 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 2S 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 boot strap power supply derived from the +15 volt supply completely eliminates the need for 3 floating independent power supplies for the high-side drive. Current sense circuitry is provided to sense current from an external resistor to shut down the bridge for overcurrent.
