MCR18EZHJ682 is a surface-mount, single-channel low-side motor driver manufactured by ROHM Semiconductor. It is designed for driving small DC motors, such as gear motors, that require low operating current. It has a wide operating voltage range of 4.5V to 50V, and a low operating current down to 10mA. The device features built-in protection functions, including short-circuit protection, over-temperature protection, and over-current protection, making it especially well-suited for use in small motor applications.
