3.7. Open-Circuit Detection
at TJ = −40 °C to +140 °C. Typical Characteristics for TJ = 25 °C, after locking the sensor
3.8. Power-On Operation
at TJ = −40 °C to +140 °C, after programming and locking. Typical Characteristics for TJ = 25 °C.
3.9. Overvoltage and Undervoltage Detection
at TJ = −40 °C to +140 °C. Typical Characteristics for TJ = 25 °C, after programming and locking
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.

1) If the supply voltage drops below V
DD,UV or rises above VDD,OV, the output voltage is switched to VDD (≥97% of VDD at RL = 10 kΩ to GND).
The CLAMP-LOW register has to be set to a voltage
≥ 200 mV.
