Description
General part information
AH1899S Series
The AH1899S is a high-sensitivity micropower, Omnipolar Hall effect switch IC with internal pull-up and pull-down capability. Designed for portable and battery-powered equipment, such as cellular phones and portable PCs, the average supply current is only 5.1µA at 1.2V and 5.8µA at 1.8V. To support portable equipment, the AH1899S can operate over the supply range of 1.1V to 2.0V and uses a hibernating clocking system to minimize the power consumption. To minimize PCB space, the AH1899S is available in a small low profile X2- DFN1010-4 (Type B) package.
