Miscellaneous
Besides the main blocks the TMC222 contains the following:
an internal charge pump used to drive the high side transistors.
an internal oscillator running at 4 MHz +/- 10% to clock the two wire serial interface, the
positioning unit, and the main control block
internal voltage reference for precise referencing
a 5 Volts voltage regulator to supply the digital logic
protection block featuring Thermal Shutdown, Power-On-Reset, etc.
