AH175-WG-7-B
Product Description
Product Overview
The AH175 is a single-digital-output Hall-Effect latch sensor designed for high-temperature operation. It features an on-chip Hall voltage generator, amplifier, comparator with hysteresis for noise rejection, and an open-collector output pre-driver. An internal band-gap regulator ensures a temperature-compensated supply voltage, enabling a wide operating supply range. The device switches its output ON when magnetic flux density exceeds the operate point (Bop) and switches OFF when the flux density reverses below the release point (Brp). It is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack), and SC59 packages.
