4 Wheel Robot Motor Driver ( 4X 3Amps LMD18201 H-Bridge)
This compact board will help you to drive 4 Wheel Drive Robots, each axis can handle a load current up to 3 Amps and supply 12V – 48 V DC. Board requires two PWM and Dir. signals for full 4WD operations, mainly differential steering for taking turns left or right or complete 360 degree rotation. The module has been designed around LMD18201 from Texas Instruments. The LMD18201 is a 3A H-Bridge designed for motion control applications. The device is built using a multi-technology process which combines bipolar and CMOS control circuitry with DMOS power devices on the same monolithic structure. Ideal for driving DC and stepper motors; the LMD18200 accommodates peak output currents up to 6A. An innovative circuit which facilitates low-loss sensing of the output current has been implemented.
