DESCRIPTION:
The MSK 4225 is a complete H-Bridge circuit to be used for DC brushed motor control or Class D switchmode amplifi-
cation. All of the drive/control circuitry for the lowside and highside switches are internal to the circuit. The 45KHz 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 4225 is constructed in a space efficient plastic power package that can be
directly bolted to a heatsink.
