It sounds like you think TI acquired LMI for the purposes of Jaguar. It didn't. TI's acquisition of LMI was for all of the microcontrollers (MCUs) that LMI developed and were selling (plus the eval kits plus the software that accompanied the eval kits, etc.). TI acquired a catalog MCU business that complements their existing MCU offerings (C2000 and MSP430).
The Jaguar speed controller is a design example of how to use one of the MCUs in a brushed DC motor control application.
