If the supply voltage drops below V
or rises above V
, the output voltage is switched to V (≥97% of V at R = 10 kΩ to GND).

The CLAMP-LOW register has to be set to a voltage ≥ 200 mV.
Note: The over- and undervoltage detection is activated only after locking the sensor!
3.10. Magnetic Characteristics
at TJ = −40 °C to +140 °C, VDD = 4.5 V to 5.5 V, GND = 0 V after programming and locking,
at Recommended Operation Conditions if not otherwise specified in the column “Conditions”.
Typical Characteristics for TJ = 25 °C and VDD = 5 V.
