CAPACITIVE LOAD
The DRV612 has the ability to drive a high capacitive load up to 220 pF directly. Higher capacitive loads can be
accepted by adding a series resistor of 47 Ω or larger for the line driver output.
LAYOUT RECOMMENDATIONS
A proposed layout for the DRV612 can be seen in the DRV612EVM User's Guide (SLOU248), and the Gerber
files can be downloaded from http://focus.ti.com/docs/toolsw/folders/print/DRV612evm.html. To access this
information, open the DRV612 product folder and look in the Tools and Software folder.
Ground traces are recommended to be routed as a star ground to minimize hum interference. VDD, VSS
decoupling capacitors and the charge-pump capacitors should be connected with short traces.
