1 Typical values are defined at TA = +25°C and VDD = 12V

2 Guaranteed by design and verified by characterization, not production tested

3 The Power-On Time represents the time from reaching VDD = VPOR to the first refresh of the supply current state.

4 Power-On Slew Rate is not critical for the proper device start-up.

5 B>BOPmax + 1 mT for direct output sensors, or B<BRPmin - 1 mT.

6 Delay Time is the time from magnetic threshold reached to the start of the supply current switching.

7 Output jitter is the unpredictable deviation of the Delay time

8 Maximum switching frequency corresponds to the maximum frequency of the applied magnetic field which is

detected without loss of pulses

9 TPROT and TREL are the corresponding junction temperature values.
