Diodes Incorporated<\/a><\/strong> introduces two new portfolios of monolithic, unipolar Hall-effect switches designed for proximity sensing in battery-powered applications. With an ultra-low 1.1\u00b5A supply current at 1.85V, and 1.6\u00b5A at 1.6V to 5.5V, these devices are ideal for battery-powered portable equipment like smartphones, laptops, and wearables. The devices are also suitable for domestic appliances, game consoles, and industrial hardware use.<\/p>\n\n\n\n

The 1.6V to 5.5V operating voltage of these Hall-effect switches allows them to be powered directly from a portable device’s battery, eliminating the area and cost of power conversion. Output 1 in the dual-output AH139x series responds to a North pole, while Output 2 responds to a South pole with typical operating points of 25G (AH1391) and 30G (AH1392). The single output on the AH138x series responds to a South pole on the part-marking side with typical operating points of 18G (AH1381), 30G (AH1382), and 45G (AH1383).<\/p>\n\n\n\n

The tight operating window of these switches ensures a lower magnetic spread, while their chopper-stabilised design provides minimal switch point drift and superior temperature stability. For robustness, these devices have strong human body model (HBM) electrostatic discharge (ESD) protection: 8kV for the AH138x and 6kV for the AH139x series. In addition, these devices have push-pull outputs that do not require an external pull-up resistor, simplifying system design, saving board space, and lowering the bill of materials.<\/p>\n","protected":false},"excerpt":{"rendered":"
