D200 H-Bridge Motor Driver Board D200 Model High Power H-Bridge DC Motor Driver Board D200 Features: Power Semiconductors: Four 110A MOSFETS Rated Current: 10A Without Heatsinks Max Current: 45A with Proper Heatsinks Installed Board's Size: 2.5" x 2.5" (6.35cm x 6.35cm). Components Type: 100% Solid State, NO Relays On Board: Filter Capacitors VTS diodes Snubber Circuit Ready Voltage Requirements: 5 Volts for the Digital and MOSFET Bias Circuits Any voltage up to 55 Volts for the Motor B+ The D200's control truth table is 100% compatible with the popular L293D motor driver IC.

For motor speed control, Pulse Width Modulation (PWM) is fully possible with the D200. The PWM signal is usually applied at the EN line. PLEASE NOTE: The only drawback for the D200 is its PWM frequency response of only 1Khz. But at its current price, we believe that you're still getting your money's worth. About the Voltage Requirements: Using the D200 D200 Schematic Join the D200 Group Most DC motor driver boards are advertised as 12, 24 or even 48 volts. That means that if you buy a board rated for 24 volts, it won't work on 12 volts and if you try to run it on 48 volts, it might be destroyed. Not the D200, the D200 can be used on applications where the motor B + can be of ANY voltage between 0 and 55 volts. The user will then use a motor rated just right for the applied voltage. If a motor of a lower rating than the motor B+ is to be used, the voltage to the motor can be brought down by pulse width modulation. Besides the Motor B+, the D200 requires a regulated 5 Volt supply for 2 reasons: 1) For the on board digital circuitry. We figured this should pose no problem, since all digital and microcontroller circuits, which we believe, will be used in conjunction with the D200, are powered by a regulated 5 Volt supply. 2) The on board DC-DC converter. This circuitry generates 3 independent 10 volt supplies for the purpose of supplying the MOSFET's gates with 10 volts no matter what the motor B+ is at in the range of 0 to 55 volts. http://www.tecel.com/d200/ (2 of 4)10/3/2007 3:46:05 AM D200 H-Bridge Motor Driver Board So you can, just by example: Safely power a 6 volt DC motor at 10 amps, without worrying about biasing the MOSFETs at 10 volts, since that is taken care of by the on board circuitry, powered by the 5 volt supply that you have to have anyways to power your other digital or microcontroller boards.
