3.8. Power-On Operation

at TJ = −40 °C to +170 °C, after programming and locking. Typical Characteristics for TJ = 25 °C.

3.9. Overvoltage and Undervoltage Detection

at TJ = −40 °C to +170 °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 +170 °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.
