AH1806-P-A

AH1806-P-A is a high-sensitivity, micro-power omnipolar hall effect switch IC, designed for portable and battery-powered consumers to home appliances and industrial applications such as smart-meter magnetic tamper detection. Based on two sensitive hall effect plates and a chopper stabilized architecture, the AH1806 provides a reliable solution over the whole operating range. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop) the output is switched on (pulled low). The output is turned off when B becomes lower than the release point (Brp). The output will remain off when there is no magnetic field. Applications include doors, lids, covers and tray position detect switches, display switch for portable PCs and tablets, on/off switch for PDAs and digital cameras, liquid level detection, smart meters, position, proximity and level detection contact-less switches in battery consumer, home appliances and industrial applications.
