DESCRIPTION:
The MSK 4401 is a 3 phase MOSFET bridge plus drivers in a convenient isolated plastic power package. The
module 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 program-
mable dead-time control for shoot-through elimination. In addition, the bridge may shut down by using the ENABLE
control. The MSK 4401 provides good thermal conductivity for the MOSFETs due to isolated plate design that allows
direct heat sinking of the device without insulators.
