DRV8808 - Combination Motor Driver

General Description

The DRV8808 device provides the integrated motor driver solution for printers.

The chip has three full Hbridges and three buck DC-DC converters.

The output driver block for each consists of Nchannel power MOSFETs configured as full Hbridges to drive the motor windings.

Key Features

  • 1 Three DC Motor Drivers.
  • Up to 2.5-A Current Chopping.
  • Low Typical ON Resistance (RDSON = 0.5 Ω at TJ = 25°C).
  • Three Integrated DC-DC Converters.
  • ON/OFF Selectable Using.
