MIL-PRF-38534 CERTIFIED
DESCRIPTION:
The MSK 4253 is a complete H-bridge MOSFET Brushed Motor Control System in an electrically isolated hermetic package. The hybrid is capable of 5 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, 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 4253 has good thermal conductivity of the MOSFET's due to isolated substrate/package design that allows direct heat sinking of the hybrid without insulators.
