Diodes Incorporated AH373
AH373 is a single-digital-output Hall-Effect latch sensor with internal pull-up resistor for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an output driver with a pull-up resistor. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop), output is switched on (OUT pin is pulled low).| Part No. | AH373 |

DESCRIPTION
An internal band-gap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range. The output state is held on until a magnetic flux density reversal falls below Brp. When B is less than Brp, the output is switched off. The AH373 is available in SIP-3L, SC59 and SOT23 packages.
