Notes: 6. Typical values are defined at TA = +25°C, VDD = 12V. Maximum and minimum values over the operating temperature range are not tested in production but guaranteed by design, process control and characterization. 7. Time from applying VDD ≥ 2.7V to the sensor until the output state is valid. 8. Time delayed from the magnetic threshold reached to the output rise or fall.
