Hello everybody. My company, SAM Controllers, has developed a full H bridge 12A DC motor driver using the VNH7100AS from ST Microelectronics Datasheet:
https://www.st.com/resource/en/datasheet/vnh7100as.pdfThe Power H Mini is a robust DC motor full H bridge driver that is useful for a variety of applications. With simple two wire control and PWM, this is a plug and play driver that ensures smoother movement of motors in each direction with complete active coupling for accuracy during precision movement. An extremely low internal resistance for the final stage provides high efficiency, low heat dissipation, and extreme recuperation of energy.
This driver provides a lot of flexibility for custom DC motor applications. It is designed for full bridge control with a single motor, for two motors to be controlled with two half bridges or for three motors to be controlled with mechanically dependent configurations. For many usage scenarios up to 5A, a heat sink can be avoided or significantly reduced.
In addition, this driver has a pinout and interface that are nearly identical to A4988, DRV8825 and similar board drivers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.
We have used this internally in our own projects and shared it among our friends. With all of the great feedback we have received, we have decided to open it up and launch it on a crowdfunding site to gain some more exposure and scale up the production.
