FEATURES:

DESCRIPTION:

System in a convenient isolated hermetic package. The controller is capable of 30 amps of output current with 75 volt rated

MOSFET transistors. 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 controller. 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. Various compensation schemes can be accommodated. 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. Possible I/O schemes are proposed below. I/O includes digital command control,

digital current monitor and digital feedback compensation values. Possible analog control includes current command, analog

current monitor output and analog feedback compensation.
