DESCRIPTION:
The MSK 4303 is a 10 Amp, 3 Phase Bridge Smart Power Motor Drive Hybrid with a 75 volt rating on the output switches. The output switches are MOSFETs. This new smart power motor drive hybrid is 5.0 volt input logic compatible. Under-voltage 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 bootstrap power supply derived from the +VB supply completely eliminates the need for 3 floating independent power supplies.

FEATURES:
• 75V, 10 Amp Capability
• Ultra Low Thermal Resistance - Junction to Case - 1.5°C/W (Each MOSFET)
• Self-Contained, Smart Lowside/Highside Drive Circuitry
• Bootstrap High-Side Supplies
• Under-Voltage Lockout
• Capable of Switching Frequencies to 25KHz
• Isolated Case Allows Direct Heat Sinking
• Bolt-down Design Allows Superior Heat Dissipation
