AH1751-WG-7-A

AH1751-WG-7-A is a single-digital-output hall-effect latch sensor for high-temperature operation. This 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, an open-collector output pre-driver. An internal band-gap regulator provides a temperature-compensated supply voltage for internal circuits and allows a wide operating supply range. It is used in applications such as rotor position sensing, current switches, encoders, and RPM detection.
