MSK4220

ISO 9001 CERTIFIED BY DSCC M.S.KENNEDY CORP. 75 VOLT 8 AMP MOSFET H-BRIDGE PWM MOTOR DRIVER/AMPLIFIER 4220 (315) 701-6751 4707 Dey Road Liverpool, N.Y. 13088 FEATURES: Low Cost Complete H-Bridge 8 Amp Capability, 75 Volt Maximum Rating Self-contained Smart Lowside/Highside Drive Circuitry Internal PWM Generation, Shoot-through Protection Isolated Case Allows Direct Heatsinking Four Quadrant Operation, Torque Control Capability Logic Level Disable Input Logic Level High Side Enable Input for Special Modulation or Function DESCRIPTION: The MSK 4220 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 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 4220 is constructed on a space efficient ceramic coated insulated metal substrate that can be directly connected to a heatsink.
