MAX14871 - 4.5V to 36V Full-Bridge DC Motor Driver - 直流电机驱动 - Industry’s Simplest and Most Flexible 4.5 to 36V DC-Brushed Motor Driver - 美信半导体
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 lowdriver on resistance reduces power during dissipation.
The MAX14871 features a charge-pump-less design forreduced external components and low supply current.Integrated current regulation allows user-defined peak startupmotor 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 thedesign and enables regulation independent of motorcharacteristics. A separate voltage sense input (SNS) reducescurrent-sensing errors due to parasitic trace resistance.
The MAX14871 features shoot-through protection andinternal free-wheeling diodes that absorb inductive motorcurrents. Driver outputs are short-circuit-protected fromshorts to ground, to the supply, and between M1 and M2.An active-low FAULT output signals thermal overload andovercurrents during fault conditions.
The MAX14871 is available in a 16-pin TSSOP-EP packageand operates over the -40°C to +85°C temperature range.
