6.3.6 Power-Up Conditions

This indicates the switch output state when there is no metal target within the switching distance of LDC0851. On power-up the LDC0851 output will be held HIGH until the part performs the sensor test and is ready for normal operation. This remains true even if the enable pin (EN) is pulled low. A HIGH to LOW transition on the OUT line occurs when the metal target comes within the switching distance of LDC0851. In the case of any sensor fault condition the LDC0851 maintains a HIGH state. An example of a sensor fault is if the sensor gets disconnected or damaged.
