9. Characterization Data Only, not tested in production
10. The coil current at a given junction temperature is calculated as: I_coil @ T_J = I_coil [1 + (T_J − 125) x I_{SET_TCi} x 10^−6].
See also paragraph Programmable Peak Current.
11. Not valid for pins with internal Pull Down resistor.
12. No more than 100 cumulated hours in life time above T_tw.
13. Thermal shutdown is derived from Thermal Warning.
