AH1889 Hall-Effect Switch


The AH1889 from Diodes provides a small, simple, and flexible contactless switch solution for multiple applications

The AH1889 is a high-sensitivity, dual-output, unipolar Hall-Effect switch IC which can detect either a north or south pole independently, and switch one of its two outputs. Designed for low-voltage consumer and industrial applications requiring fast response (without sleep mode), the AH1898 has been optimized to operate over the supply range of 1.6 V to 3.6 V, and without sleep function. Based on chopper-stabilized architecture and an ESD rating of 4 kV, the AH1898 provides a reliable and robust solution over the whole operating range. To help achieve the small solution, the AH1889 has internal push-pull output, therefore avoiding external pull-up. It is available in the small, low-profile SOT553 packages.
