DESCRIPTION:
The MSK4370 is a complete 3 Phase IGBT Bridge Brushless Motor Control System in a convenient isolated baseplate
package. The device is capable of 10 amps of output current and 500 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 cur-
rent sensing and analog circuitry necessary for closed loop current mode (torque) control. When PWM'ing, the transistors
are modulated in locked anti-phase (complementary) mode for the tightest control and the most bandwidth. Provisions for
applying different compensation schemes are included. The MSK4370 has good thermal conductivity of the IGBT's due to
a hermetic isolated package design that allows direct heat sinking of the device without insulators.
