Product Specification
| Operating Current | 8uA | Operating Temperature | -40℃~+125℃ |
| Voltage - Supply | 2.5V~5.5V | Magnetic Field Range | ±18.5mT |
| Description | SIP-3 Switches (Solid State) RoHS | Mfr. Part # | AH1809-P-B |
| Package | SIP-3 | Model Number | AH1809-P-B |
The AH1809 is a low sensitivity, micropower Omnipolar Hall Effect switch IC designed for battery-powered consumer products, home appliances, and industrial equipment such as smart e-meters. It offers a reliable solution over its operating range due to its two Hall Effect plates and chopper-stabilized architecture. Optimized for battery and low-power applications, it operates from a 2.5V to 5.5V supply and consumes only 24W at 3V. The single open-drain output switches on with either a North or South magnetic pole and turns off when the magnetic flux density falls below the release point. The output remains off in the absence of a magnetic field.
