Diodes Hall effect switch AH1892 makes portable products more smart

DioDes launches the smallest programmable, and the full polar Hall effect switch. This AH1892 device is suitable for space-restricted portable and battery-driven products, including tablet, smartphones, and cameras, especially suitable for close effects and position detection. AH1892 is a micro-power device with miniature four-pointed foot 0.7 x 0.7 x 0.5 mm U-WLB0707-4 package, the volume is 17 times larger than the general three-pin TSOT package product. The integrated pull-up resistor integrated with this switching device helps simplify the layout of the external circuit, and can also reduce the area of ​​the printed circuit board, thereby further saving the packaged placeholder space. The device is equipped with a simple range selection pin that can be programmed to one of the two preset magnetizable ranges to accommodate different magnetic field strength applications. Sensitivity can vary from external logic such as microcontrollers at any time during operation. The AH1892 is optimized for low voltage portable and battery-powered products, which can operate within 1.6V to 3.6V. Under normal operation, the average power consumption of this switch is only 4.3 μA to extend the battery life. The device can provide 8kV electrostatic discharge protection on the power supply and output pin, which helps to enhance the product in the manufacturing process and the reliability of use. The Hall effect closing point and release point of AH1892 can maintain a high level of stable in a wide temperature range of -40oC to 85oC; the possibility of premature or too late switches can be avoided. The device uses chopper design to effectively counter RF noise and other circuit stress. AH1892 In addition to micro U-WLB0707-4 packages, there is also a standard slim SOT553 package. High sensitivity version of the model is AH1894, providing SOT553 and DFN1216-4 package selection, will start from this year later.
