Product Summary
The DRV8808DCA is a combination motor driver with dc-dc converter. The device provides the integrated motor driver solution for printers. The DRV8808DCA has three full H-bridges and three buck DC-DC converters. The output driver block for each consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings. The DRV8808DCA can be configured to utilize internal or external current sense for winding current control.
