DESCRIPTION:
The MSK4362 is a complete 3 Phase MOSFET Bridge Brushless Motor Control System in a convenient isolated hermetic
package. The device 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, hall sensing circuitry, commutation 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 com-
pensation schemes are included. The MSK4362 has good thermal conductivity of the MOSFET's due to isolated package
design that allows direct heat sinking of the device without insulators.
