RobinHart over 3 years ago

Hello. Please can someone advise a circuit to latch the high output of an A3144 Hall Effect sensor ? Using a thyristor maybe ?

You could use this circuit, that uses asingle opamp as Set-Reset with configurable input HI level: https://www.edn.com/use-an-op-amp-as-a-set-reset-flip-flop/

Take care that you configure the output pull-up voltage of the sensor in range for the input of the latching circuit.
