6. Tested in production for 800 mA, 400 mA, 200 mA and 100 mA current settings for both X and Y coil.
7. Based on characterization data.
8. No more than 100 cumulated hours in life time above T_tw.
9. Thermal shutdown and low temperature warning are derived from thermal warning. Guaranteed by design.
10. A buffer capacitor of minimum 100 mF is needed between V_BB and GND. Short connections to the power supply are recommended.
11. Pin V_DD must not be used for any external supply
12. The RAM content will not be altered above this voltage.
13. External resistance value seen from pin SWI or HW2, including 1 kW series resistor. For the switch OPEN, the maximum allowed leakage
current is represented by a minimum resistance seen from the pin.
