Brushed DC Torque Controller -- MSK4250-Image

The MSK 4250 is a complete H-bridge MOSFET Brushed Motor Control System in an electrically isolated hermetic package. The hybrid is capable of 10 amps of output current and 75 volts of DC bus voltage. It has the normal features for protecting the bridge. Included is all the bridge drive circuitry, and all the current sensing and analog circuitry necessary for closed loop current mode (torque) control. When PWM'ing, the transistors are modulated in locked anti-phase mode for the tightest control and the most bandwidth. Provisions for applying different compensation schemes are included. The MSK 4250 has good thermal conductivity of the MOSFET's due to isolated substrate/package design that allows direct heat sinking of the hybrid without insulators.

FEATURES:

  • 75 Volt Motor Supply Voltage
  • 10 Amp Output Switch Capability
  • 100% Duty Cycle High Side Conduction Capable
  • Shoot-Through/Cross Conduction Protection
  • "Real" Four Quadrant Torque Control Capability
  • Good Accuracy Around the Null Torque Point
  • Contact MSK for MIL-PRF-38535 Qualification Status

TYPICAL APPLICATIONS:

  • Brushed DC Motor Control
  • Servo Control
  • Fin Actuator Control
  • Voice Coil Control
  • Gimbal Control
  • AZ-EL Control
