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.}
