PW-82336 Radiation Tolerant Smart Power 3-Phase Motor Drive


Part Number(s): PW-82336

The PW-82336 is a 3-phase Motor Drive hybrid that utilizes a rad-tolerant MOSFET output stage with 100 VDC rating to deliver 5A continuous current to the motor. 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.


  • Flexible I/O Allows Common Design to be Used Across Multiple Application Platforms
  • 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 the High and Low-side Gate Drivers for each Phase and Operate from +5 to +15 V Logic Levels
  • Constant Output Performance for Switching Frequencies from DC to 50kHz Provided by the Internal Charge Pump Circuitry
