DESCRIPTION:
The MSK 4301 is a 3 phase MOSFET bridge plus drivers in a convenient isolated hermetic package. The hybrid is
capable of 29 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 Enable control. The MSK 4301 provides
good thermal conductivity for the MOSFETs due to the electrically isolated package design that allows direct heat sinking
of the device without insulators.
