AH1815-P-B

AH1815-P-B is a low-sensitivity, micro-power omnipolar hall effect switch IC, designed for portable and battery-powered consumer equipment for 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 AH1815 provides a reliable solution over the whole operating range. When the magnetic flux density (B) perpendicular to the package is larger than operating point (Bop) the output is switched on (pulled low). The output is turned off when B becomes lower than the releasing 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 for coffee machines, position, proximity and level detection contactless switch, home appliances and industrial applications.

• Single open-drain output can switch on with either a north or south pole of sufficient strength
• Low sensitivity, micropower operation
• 2.5V to 5.5V operating range
• Chopper stabilized design provides superior temperature stability
• Minimal switch point drift, enhanced immunity to stress
• Good RF noise immunity, ESD (HBM) > 6KV
• Output leakage current is < 0.1µA typ at VOUT = 5.5V, output off, TA = +25°C, VDD = 3V
• Average supply current is 8µA typ at TA = +25°C, VDD = 3V
• SIP-3 package
• Operating temperature range from -40 to +125°C
