DESCRIPTION:
The MSK 4365 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 30 amps continuous output current with 75V
absolute maximum rated MOSFETs, allowing a 50V 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. Compen-
sation values are analog inputs and are read in by the processor upon start up or after releasing RESET. The MSK4365 has
good thermal conductivity for MOSFET power dissipation due to the isolated package design that allows direct heat sinking
of the device without insulators. Current command input is an analog input read by the processor and current monitor
output is analog as well.
