DESCRIPTION:
The MSK 4252 is a complete H-bridge MOSFET Brushed Motor Control System in an electrically isolated hermetic
package. The hybrid is capable of 30 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
4252 has good thermal conductivity of the MOSFET's due to isolated substrate/package design that allows direct heat
sinking of the hybrid without insulators.
