Am I following the procedure to set the sensitivity in Try Mode for the A1362 Hall-Effect sensor correctly?
I am following Figure 5 pg. 18 of this data sheet: Vp(HIGH), Vp(MID), Vp(HIGH), followed by 0-255 Vp(MID) pulses that increase the sensitivity each time Vp(MID) is applied.
However, when I bring ...

Why do my 3 custom voltage pulses stop working as soon as I plug in the A1362 Hall-Effect sensor?
Why does the Vout pin in the diagram below receive 8 volts with Vcc = 0 volts, but becomes 2 volts when Vcc=5 volts. If switch SW9 is closed, circuit theory says Vout should always stay at 15 volts ...
