The AH174 is a single‑digital‑output Hall‑effect sensor designed for high‑temperature operation. It features a bipolar Hall element, open‑collector pre‑driver, 25 mA output sink current, and reverse‑connection protection, with a supply range of 3.5 V to 20 V.
Typical applications include rotor‑position sensing, current switching, encoder feedback, and RPM detection. The device is offered in SIP‑3 and SOT‑23 packages and can be ordered using the part number format AH174 X‑XXX‑X.
