DESCRIPTION:

MIL-PRF-38534 CERTIFIED

sulated 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 4251 has good thermal conductivity of the MOSFET's due to the electrically isolated substrate/package

design that allows direct heat sinking of the hybrid without insulators.
