The MAX14872ETC+T from Analog Devices is a Full-Bridge DC Motor Driver that has been designed for driving and controlling brushed DC motors and relays. It requires an input voltage of 4.5 - 36 V. This motor driver has a charge-pump-less design to ensure reduced external components and low supply current, enabling a compact drive operation. It allows fast-decay current regulation to adjust the peak startup motor current. This motor driver has a voltage-sense input to reduce current sensing errors due to parasitic trace resistance. It includes internal free-wheeling diodes to absorb inductive motor currents.
This motor driver is equipped with forward and reverse inputs for direction control. It integrates short-circuit protection, thermal shutdown, and under-voltage lockout (UVLO) for high reliability. This motor driver IC is available in a surface-mount package that measures 3 x 3 mm and is ideal for printers and scanners, relay drivers, vending machines, and gaming machine applications.
