App note: Motor pre-drivers vs integrated drivers

Posted on Sunday, December 16th, 2012 in app notes by DP

Here is a video from Texas Instruments describing the differences in motor pre-drivers vs integrated drivers. Pre-drivers have all the control circuitry but the FETs are external, while in integrated drivers everything is on one IC. Because pre-drivers use external FETs, you can select the ones with much lower RDS-on resistance. This will give you much better thermal characteristics, but you sacrifice board space.
