DESCRIPTION  
The DRV8808 provides the integrated motor driver solution for printers. The chip 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 device can be configured to utilize internal or external current sense for winding current  
control.  
The SPI input pins are 3.3-V compatible and have 5-V-tolerant inputs.  
The DRV8808 has three dc-dc switch-mode buck converters to generate a programmable output voltage from  
1 V up to 90% of VM, with up to 1.35-A load current capability.  
The device is configured using the CSELECT terminal at start up, and serial interface during run time.  
An internal shutdown function is provided for overcurrent protection, short-circuit protection, undervoltage lockout,  
and thermal shutdown. Also, the device has the reset function at power on, and the input on nReset pin.
