5.1.12 Temperature Management
The TMC223 provides an internal temperature monitoring. The circuit goes into shutdown mode if the
temperature exceeds threshold T
tsd
, furthermore two thresholds are implemented to generate a
temperature pre-warning.
Low Temperatur

<TW> = '0'
<TSD> = '0'
Normal Temp.
