Unipolar Corridor impact switches from Diodes function over a provide vary of 1.6 V to five.5 V with a median provide present of simply 1.1 µA at 1.85 V. The low-power units are designed for proximity sensing in battery-powered units, together with smartphones, laptops, and wearables. Their extensive working voltage vary permits them to be powered straight from a tool’s battery.
Output 1 within the dual-output AH139x collection responds to a north pole, whereas output 2 responds to a south pole. Typical working factors for the AH1391 and AH1392 are 25 G and 30 G, respectively. The one-output AH138x collection responds to a south pole on the part-marking aspect with typical working factors of 18 G (AH1381), 30 G (AH1382), and 45 G (AH1383).
Based on the producer, the tight working window of those switches ensures a decrease magnetic unfold. Their chopper-stabilized design supplies minimal switch-point drift and ensures temperature stability. Additional, the elements have push-pull outputs that don’t require an exterior pull-up resistor.
Appropriate for small form-factor purposes, the entire Corridor switches are provided in compact DFN1010-4 and DFN1410-4 packages. AH138x units are moreover accessible in SOT23 packages. The AH1391 and AH1392 in DFN packages price $0.18 every in a number of 1000 items. The AH1381, AH1382, and AH1383 price $0.17 for DFN variations and $0.16 for SOT23 variations in like portions.
