MAX14870 - Compact 4.5V to 36V Full-Bridge DC Motor Drivers

General Description

The MAX14870/MAX14872 motor drivers provide a small, low-power and simple solution for driving and controlling brushed DC motors and relays with voltages between 4.5V and 36V.

Very low driver on-resistance reduces power dissipation.

Key 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 MAX14870 has PWM and direction-control inputs, while the MAX14872 has forward and reverse inputs for direction control. See the Function Tables. The MAX14870/MAX14872 are available in a 12-pin (3mm x 3.

EVALUATION KIT AVAILABLE MAX14870/MAX14872 Compact 4.5V to 36V Full-Bridge DC Motor Drivers General Description The MAX14870/MAX14872 motor drivers provide a small, low-power and simple solution for driving and controlling brushed DC motors and relays with voltages between 4.5V and 36V. Very low driver on-resistance reduces power dissipation. These drivers feature a charge-pump-less design for reduced external components and low supply current. Integrated fast-decay current regulation allows useradjustable peak startup motor currents and requires minimal external components. A separate voltage-sense input (SNS) reduces current sensing errors due to parasitic trace resistance.
