Trinamic Motion Control MPN encoding patterns, motor driver series decoding, and handler guidance. Use when working with Trinamic stepper drivers and motion controllers (TMC series).
Trinamic (now part of Analog Devices) specializes in motor control ICs:
TMC[FAMILY][SERIES]-[PACKAGE][-SUFFIX]

Example: TMC2209-LA
| | | |
| | | +-- LA = QFN package
| | +-- 09 = Series number
| +-- 2 = Stepper driver family
+-- TMC = Trinamic prefix
Example: TMC5160-TA-T
| | | | |
| | | | +-- T = Tape and reel packaging
| | | +-- TA = TQFP package
| | +-- 60 = Series (motion controller)
| +-- 5 = Motion controller family
+-- TMC = Trinamic prefix
