Low voltage, simple to use 1A dual motor (or bipolar stepper) driver board with break option.

Perfect driver for mini sumo robots or other geared motor applications.

Description

The Sanyo LB1836M is a dual low-voltage H-bridge that can be used for bidirectional control of two DC motors or one bipolar stepper motor. With an operating voltage as low as 2.5 V for logic and 1.8 V for the motor(s), this controller is great for small motors powered from a single Li-based battery or 2-6 NiMH or alkaline cells. The peak current is up to 1 A per channel, but thermal dissipation usually limits the available continuous current to around 0.5 A (this depends on the PCB layout and heat sinking).

The motor driver features thermal shutdown that can help the chip withstand over-current and short-circuit situations. The IC is only available in a surface-mount package, but the 1.0 mm pitch is relatively accessible even with a standard soldering iron, making it an attractive option for those wanting to build small motion control systems.
