AH173 Datasheet | Diodes Incorporated

Description AH173 is a single-digital-output Hall effect latch sensor with pullup resistor for high-temperature operation. The device includes an onchip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, a parator to provide switching hysteresis for noise rejection, and an output driver with a pullup resistor (Rpu). An internal bandgap regulator provides a temperature pensated supply voltage for internal circuits and allows a wide operating supply range. When the magnetic flux density (B) is larger than operate 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 AH173 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack), and SC59 packages.
