DESCRIPTION:
The MSK4310 is a complete 3 Phase Brushless Motor Speed Controller in an electrically isolated hermetic package. The
hybrid is capable of 10 amps of output current and 55 volts of DC bus voltage. Included is all of the bridge drive circuitry, hall
sensing circuitry and commutation circuitry. Also included is a user programable current limit circuit and a tachometer circuit for
closed loop operation. The MSK4310 has good thermal conductivity of the output switches due to isolated substrate/package
design that allows direct heat sinking of the hybrid without insulators.
