Hi Alexey,
according to KL4x fact sheet
http://www.freescale.com/files/microcontrollers/doc/fact_sheet/LSERIESKL4FS.pdf?fpsp=1&WT_TYPE=F...
TSI device is not available on the KL43 derivatives . This device is available on KL46 derivatives only.

so fsl_tsi component is not available on the KL43 derivative.
does this answer your question?
Have a great day,
Zhang Jun
