8. Tested in production for 800 mA, 400 mA, 200 mA and 100 mA current settings for both X and Y coil.
9. Not measured in production. Guaranteed by design.
10. Parameter guaranteed by trimming relevant OTP’s in production test at 143°C (±5°C) and V_BB = 14 V.
11. No more than 100 cumulated hours in life time above Tw.
12. Thermal shutdown and low temperature warning are derived from thermal warning. Guaranteed by design.
13. A buffer capacitor of minimum 100 mF is needed between V_BB and GND. Short connections to the power supply are recommended.
