DESCRIPTION:
The MSK 4300 is a 3 phase MOSFET bridge plus drivers in a convenient isolated hermetic package. The hybrid is
capable of 10 amps of output current and 75 volts of DC bus voltage. It has a full line of protection features,
including undervoltage lockout protection of the bias voltage, cross conduction control and a user programmable
dead-time control for shoot-through elimination. In addition, the bridge may be shut down by using the EN (enable)
control. The MSK 4300 provides good thermal conductivity for the MOSFETs due to the electrically isolated package
design that allows direct heat sinking of the device without insulators.
