Compact, High-Reliability Radiation Tolerant Smart Power 3-Phase Motor Drive

Bohemia, New York (June 2016) Data Device Corporation (DDC) introduces a new high-reliability, 3-phase radiation tolerant motor drive, providing 100k Rad Total Dose protection, and advanced circuit and logic protection to ensure fail-safe operation. The new compact PW-82336 3-phase motor drive hybrid utilizes a high-efficiency, radiation tolerant MOSFET output stage with 100 VDC rating to deliver 5A continuous current (10A peak current) to the motor, along with flexible I/O, enabling a common design to be used across multiple applications.


  • Flexible I/O allows common design to be used across multiple application platforms with individual bridge returns and standard logic level inputs to facilitate design implementation
  • Eliminates shoot-through conditions with high and low-side input logic signals XOR's in each phase to prevent simultaneous turn on of in-line transistors
  • Internal logic controls (from +5 to +15 V ) for the high and low-side gate drivers for each phase
  • Constant output performance for switching frequencies from DC to 50kHz provided by the internal charge pump circuitry
  • 100VDC rating with 5A continuous, 10A peak current capability
  • 100k Rad Total Dose (Si)
  • Small size: 66 x 35.6 x 6.35 mm (2.6 x 1.4 x 0.25 in)

“Packaged in a small case with internal logic for optimized performance, this high-reliability motor drive is an excellent choice for servo-amplifiers and speed controls in high performance space, aerospace and military applications” stated Vincent Giardini, DDC Product Line Director, Motor Control Solutions.
