DESCRIPTION:
The MSK 4200 is a complete H-Bridge hybrid to be used for DC brushed motor control or Class D switchmode amplifier. All of the drive/control circuitry for the lowside and highside switches are internal to the hybrid. 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 4200 is packaged in a space efficient isolated 8 pin TO-3 that can be directly connected to a heatsink.

APPLICATION NOTES MSK 4200 PIN DESCRIPTION
VCC - Is the low voltage supply for powering internal logic and drivers for the lowside and highside MOSFETS. The supplies for the highside drivers are derived from this voltage. V+ - Is the higher voltage H-bridge supply. The MOSFETS obtain the drive current from this supply pin. The voltage on this pin is limited by the drive IC. The MOSFETS are rated at 100 volts. Proper bypassing to GND with sufficient capacitance to suppress any voltage transients, and to ensure removing any drooping during switching, should be done as close to the pins on the hybrid as possible.
MOTOR A - Is the output pin for one half of the bridge. Increasing the input voltage causes increased duty cycles at this output. MOTOR B - Is the output pin for the other half of the bridge. Decreasing the input voltage causes increased duty cycles at this output.
RSENSE A - This is the connection for the bottom of the A half bridge. This can have a sense resistor connected to the V+ return ground for current limit sensing, or can be connected directly to ground. The maximum voltage on this pin is 2 volts with respect to GND.
IN
GND - Is the return connection for the input logic and Vcc. RSENSE B - This is the connection for the bottom of the B half bridge. This can have a sense resistor connected to the V+ return ground for current limit sensing, or can be connected directly to ground. The maximum voltage on this pin is 2 volts with respect to GND.
INPUT - Is an analog input for controlling the PWM pulse width of the bridge. A voltage higher than Vcc/2 will produce greater than 50% duty cycle pulses out of MOTOR A. A voltage lower than Vcc/2 will produce greater than 50% duty cycle pulses out of MOTOR B.

TYPICAL SYSTEM OPERATION
This is a diagram of a typical application of the MSK 4200. The design Vcc voltage is +12 volts and should have a good low ESR bypass capacitor such as a tantalum electrolytic. The analog input can be an analog speed control voltage from a potentiometer, other analog circuitry or by microprocessor and a D/A converter. This analog input gets pulled by the current control circuitry in the proper direction to reduce the current flow in the bridge if it gets too high. The gain of the current control amplifier will have to be set to obtain the proper amount of current limiting required by the system. Current sensing is done in this case by a 0.1 ohm sense resistor to sense current from both legs of the bridge separately. It is important to make the high current traces as big as possible to keep inductance down. The storage capacitor connected to the V+ and the hybrid should be large enough to provide the high energy pulse without the voltage sagging too far. A low ESR ceramic capacitor or large polypropylene capacitor will be required. Mount capacitor as close to hybrid as possible. The connection between GND and the V+ return should not be carrying any motor current. The sense resistor signal is common mode filtered as necessary to feed the limiting circuitry for the microprocessor. This application will allow full four quadrant torque control for a closed loop servo system. A snubber network is usually required, due to the inductance in the power loop. It is important to design the snubber network to suppress any positive spikes above 75V and negative spikes below -2V with respect to pin 5 (gnd).
