This was a customized prototyping project and the requirement was to design and develop a Dual H Bridge Drive to run thrusters of an under water remotely operated vehicle.
The clients requirement was to compete the project with the lowest component count and still have all features like short circuit prevention, over current limiting and minimum heat dissipation. Considering the fact that this was to be used in a under water enclosure with little option for heat dissipation. The ROV was run by two thrusters each requiring upto 6A continuous current and peak currents of upto 12A. Our designers identified TI’s DRV8432, which fit the bill perfectly with the least possible component count, good thermal characteristics and very easy to use control signals that did not require much customization of the clients code.
