AH372 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. An internal band-gap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
When the magnetic flux density (B) perpendicular to the package is larger than operation point (BOP), output is switched on (OUT pin is pulled low). 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 AH372 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack), SC59 and SOT23 packages.
