Maximum Coil Resistence for Coil Detection
Notes: 1. Some parametric limits are design targets that may be refined on the basis of production history.
2. Coil voltages are measured with respect to the on chip ground, which is centered on the AC voltage from the coil.
Peak-to-peak coil voltages would be double those listed above.
