The Power H Mini is a robust DC motor full H bridge driver that is useful for a variety of applications where electromechanical control is required. With a simple two wire control and PWM, this plug and play driver 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. With a peak current limit of 12A, this board delivers a surprising amount of motor control in a tiny package.
|Output motor voltage range||4 to 28 V|
|Logic level on IN pins||up to 5.5 V|
|Peak Current||12 A|
|Stand-by current (max)||1 µA|
This product is intended for users looking for a full H-bridge driver in a small form factor (15mm x 20mm) that drives DC motors up to 12A with excellent thermal dissipation.
With an encoder and your controller, this becomes a complete servo motor solution on a board, ideal for prototyping with DC motors to build a feedback system that is much smoother motor movement with a more predictable pathway.
