DESCRIPTION:

The MSK 4225 is a complete H-Bridge circuit to be used for DC brushed motor control or Class D switchmode amplification. 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.
