4707 Dey Road Liverpool, N.Y. 13088
FEATURES:
75 Volt Motor Supply Voltage
29 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
DESCRIPTION:
The MSK 4401 is a 3 phase MOSFET bridge plus drivers in a convenient isolated baseplate 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 programmable
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.
