MOSFET BRUSHLESS

MOTOR CONTROLLER

EQUIVALENT SCHEMATIC

DESCRIPTION:

The MSK 4460 is a complete 3 Phase MOSFET Bridge Brushless Motor Control System in an electrically isolated

low cost package. The hybrid is capable of 10 amps of output current and 55 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 current sensing and analog circuitry necessary for closed loop current mode (torque) control.

When PWM'ing, the transistors are modulated in locked anti-phase mode for the tightest control and the most

bandwidth. Provisions for applying different compensation schemes are included. The MSK 4460 has good thermal

conductivity of the MOSFET's due to isolated substrate/package design that allows direct heat sinking of the hybrid

without insulators.

FEATURES:

55 Volt Motor Supply Voltage

10 Amp Output Switch Capability

100% Duty Cycle High Side Conduction Capable

Shoot-Through/Cross Conduction Protection
