Product Overview

The MAX14871EUE+T is a 4.5V to 36V full-bridge DC motor driver in 16 pin TSSOP package. The DC motor driver provides a low-power and simple solution for driving and controlling brushed motors. Charge pumpless design for reduced external components and low supply current. Integrated current regulation allows user-defined peak start-up motor currents and requires minimal external components. It includes 3 modes of current regulation of fast decay, slow decay and 25% current ripple modes. Current regulation based on 25% ripple simplifies design and enables regulation independent of motor characteristics. A separate voltage sense input (SNS) reduces current-sensing errors due to parasitic trace resistance. Shoot-through protection & internal free-wheeling diodes that absorb inductive motor currents. Driver outputs are short circuit protected from shorts to ground, to supply and between M1 and M2. An active-low FAULT output signals thermal overload and overcurrents during fault conditio
  • Supply voltage range is 4.5V to 36V
  • Operating temperature range from -40°C to 85°C
  • Up to 2.8A peak motor current package
  • Total bridge on-resistance is 334Mohm (typ)
  • Supply current is 1mA (typ) at 30KHz/24V
  • Standby current is 10µA (max) at 12V
  • Current regulation only requires a sense resistor
  • Current sense input simplifies PCB layout
  • Internal/external VREF for current regulation
