AH1911中文资料MICROPOWER OMNIPLOAR HALL-EFFECT SWITCH数据手册Diodes规格书

描述 Description

The AH1911 is an ultra-low power digital Omnipolar Hall Effect switch IC from Diodes broad Hall Effect switches family. Thanks to the hibernating clocking system, the average supply current is only 1.6μA at 3V, which makes the AH1911 perfectly fit battery-powered consumer products, Gas or water meter, smoke detectors and IoT devices. The wider range of supply voltage (1.6V to 5.5V) extends battery operating time and supports low voltage system microcontrollers, which provides great flexibility for system design. The advanced chopper stabilized design provides superior stability on switch operating point over temperature and supply voltage. The high ESD level up to 6KV helps to improve the system robustness.The single push pull output can be switched on with either South or North pole of sufficient strength. When the magnetic flux density (B) perpendicular to the package is larger than operate point (BOP), the output will be turned on (pulled low) and held until B is lower than release point (BRP).The AH1911 comes with the industry-standard SC59 package.
