Abstract

When designing systems with integrated FET drivers, thermal performance can be a major consideration if users need the BLDC driver to operate with the most efficiency. At the most basic level, driving significant amounts of current from an integrated FET driver can only be possible if the device settings and parameters are optimized. This application note presents lab data showing how several of the customizable parameters on Texas Instruments’ DRV8316 and DRV8317 affect the thermal performance of the devices.
