DESCRIPTION:
The MSK4301 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 MSK4301 provides good thermal
conductivity for the MOSFETs due to the electrically isolated package design that allows direct heat sinking of the device
without insulators.
