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.

OUTPUT CURRENT RECOMMENDATION (PW PACKAGE) TA = 25°C
