DRV8808 - Texas Instruments

DRV8808 Combination Motor Driver

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. The device can be configured to use internal or external current sense for winding current.
