600 V IGBT 3-Phase motor drive hybrid

The MSK 4454 is a 10 A, 600 V IGBT smart power three-phase motor drive hybrid. This device features ultra low thermal resistance, self-contained, small lowside/highside drive circuitry, bootstrap high-side supplies, under-voltage lockout, isolated case that allows direct heat sinking, and non-hermetic bolt-down design that permits superior heat dissipation. The output switches of the device are Insulated Gate Bipolar Transistors (IGBT’s). 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. 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.
