MAX14871 Full-Bridge DC Motor Driver

Analog Devices MAX14871 Full-Bridge DC Motor Driver provides a low-power, simple solution for driving and controlling brushed motors. The motors can have voltages between 4.5V and 36V. This driver has a very low driver on resistance, which reduces power during dissipation. This device features a charge-pump-less design for reduced external components and low supply current. The integrated current regulation allows user-defined peak startup motor currents and requires minimal external components. The MAX14871 includes three modes of current regulation: fast decay, slow decay, and 25% current ripple modes. Current regulation is based on a 25% ripple, simplifies the design, and enables regulation independent of motor characteristics.
