FEATURES:

DESCRIPTION:

75 Volt Motor Supply Voltage

10 Amp Output Switch Capability, All N-Channel MOSFET Output Bridge

100% Duty Cycle High Side Conduction Capable

Suitable for PWM Applications from DC to 100KHz

Shoot-Through/Cross Conduction Protection

Undervoltage Lockout Protection

Programmable Dead-Time Control

Low Active Enable for Bridge Shutdown Control

Isolated Base Plate Design for High Voltage Isolation Plus Good Thermal Transfer

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.
