75 VOLT 10 AMP MOSFET
H-BRIDGE PWM MOTOR
DRIVER/AMPLIFIER
4224
The MSK 4224 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
250KHz 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 4224 is constructed on a space efficient
ceramic coated insulated metal substrate that can be directly connected to a heatsink.
