Diodes Incorporated AH1812
The AH1812 is a high sensitivity micropower Omnipolar Hall effect switch IC with an open drain output. Designed for portable and battery powered equipment such as cellular phones and portable PCs, the average supply current is only 4.3µA at 1.85V. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop), the output will be turned on (pulled low).| Part No. | AH1812 |

DESCRIPTION
To support potable equipment the AH1812 can operate over the supply range of 1.6V to 3.6V and uses a hibernating clocking system to minimize the power consumption. To minimize PCB space the AH1812 is available in small low profile X1-DFN1216-4 package The open drain output is activated with either a North or South pole of sufficient magnetic field strength. 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.
