DESCRIPTION:

The MSK 4400 is a 3 phase MOSFET bridge plus drivers in a convenient isolated baseplate package. The module 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 ENABLE control. The MSK 4400 provides good thermal conductivity for the MOSFETs due to an isolated plate design that allows direct heat sinking of the device without insulators.
