DESCRIPTION:
The MSK4366 is a non-isolated, completely digitally controlled 3 Phase Brushless DC Motor Control Torque Amplifier in
a convenient isolated hermetic package. The controller is capable of 10 amps continuous output current with 55V absolute
maximum rated MOSFETs, allowing a 38V maximum motor supply voltage. Bridge protection is included. The digital signal
processor controls the hall sensing, commutation, current sensing and PWM control for a complete closed loop, current
mode torque amplifier. The PWM scheme used by the processor is "Locked Anti-Phase Full Complementary" digital PWM.
This provides full four quadrant control of the motor around zero torque without losing loop control. The MSK4366 has good
thermal conductivity for MOSFET power dissipation due to the isolated package design that allows direct heat sinking of
the device without insulators.
