Description
The MAX14871 DC motor driver provides a low-power and simple solution for driving and controlling brushed motors with voltages between 4.5V and 36V. Very low driver on resistance reduces power during dissipation. The MAX14871 features a charge-pump-less design for reduced external components and low supply current. Integrated current regulation allows user-defined peak startup motor currents and requires minimal external components. The MAX14871 includes 3 modes of current regulation: fast decay, slow decay, and 25% current ripple modes. Current regulation based on 25% ripple simplifies the design and enables regulation independent of motor characteristics. A separate voltage sense input (SNS) reduc- es current-sensing errors due to parasitic trace resistance. The MAX14871 features shoot-through protection and internal free-wheeling diodes that absorb inductive motor currents. Driver outputs are short-circuit-protected from shorts to ground, to the supply, and between M1 and M2. An active-low FAULT output signals thermal overload and overcurrents during fault conditions. The MAX14871 is available in a 16-pin TSSOP-EP package and operates over the -40°C to +85°C temperature range.
