Overview

The AH175 is a single-digital-output Hall-Effect latch sensor designed for high-temperature operation. It features an integrated Hall voltage generator, amplifier, comparator with hysteresis for noise rejection, and an open-collector output pre-driver. A band-gap regulator ensures a temperature-compensated supply voltage and a wide operating supply range. The device switches its output low when magnetic flux density exceeds the operate point (Bop) and remains low until the flux density falls below the release point (Brp), at which point it switches off. The AH175 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack), and SC59 packages.

Product Attributes
