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.
