DESCRIPTION:
The MSK 4454 is a 10 Amp, 3 Phase Bridge Smart Power Motor Drive Hybrid with a 600 volt rating on the
output switches. The output switches 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 speci-
fied 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.
