8.3 Feature Description
8.3.1 Recommended Output Current
DRV8860 current capability will depend on several system application parameters such as system ambient
temperature, maximum case temperature, and overall output duty cycle. The PWP package provides a better
heatsinking capability through the PowerPAD™; and therefore, is cable of driving higher output current or
operating at a slightly lower temperature than the device in PW package.
