[M.S.KENNEDY CORP.]

DESCRIPTION:

The MSK 4202RH is a radiation hardened complete H-Bridge hybrid intended for use in DC brushed motor control applications or Class D switchmode amplification in space or other severe operating environments. The design will exhibit high resistance to Single Event Effects (SEE), Single Event Gate Rupture (SEGR), total dose up to 100K RAD and neutron tolerance for military applications. All of the drive/control circuitry for the lowside and highside switches are internal to the hybrid, as well as a +5V linear regulator. The PWM circuitry is internal as well, leaving the user to only provide an analog signal for the motor speed/direction, or audio signal for switchmode audio amplification. The MSK 4202RH is packaged in a space efficient isolated 18 pin power package available in three lead form configurations that can be directly connected to a heatsink.
