CODING INTERNATIONAL CO LTD

Six high-performance Hall effect sensor switches from Diodes AG are designed to preserve power in position and also proximity detection jobs in a variety of consumer, property appliance and industrial equipment. Optimized for a supply voltage vary from 1.6V to 3.6V and using a hibernating clocking technique to minimize power consumption, the switches’ average provide current is typically 4.3 μA at 1.8V.

The micropower Hall effect product introduction comprises the medium-sensitivity AH1895 and high-sensitivity AH1893, AH1897 and AH1812 omnipolar switches, the prrr-rrrglable high-sensitivity AH1894 omnipolar switch and the AH3360, the high-sensitivity unipolar (south pole) move. These simple items are offered in space-saving and also low-profile X1-DFN1216-4 (1.2 mm x 1.6 mm x 3.5 mm) and also leaded SOT553 (1.6 mm x 1.6 mm x 0.5 mm) deals.

All devices, aside from the AH1812, include an inner push-pull output structure, which helps a reduction in external element count and a simplification of PCB styles. The AH1812 provides an open-drain output option for added flexibility in system pull-up.

The chopper-stabilized design means these kinds of highly integrated gadgets offer improved temperatures stability, immunity to fret effects and small drift across their particular operating temperature array of -40ºC to +85ºC. Protection against ESD can be high at 8 kV, helping to improve item robustness and simplifying coping with during manufacture.

Delivering additional design overall flexibility, the programmable-variant AH1894 enables consumers to select between one of two magnetic sensitivity ranges using a band select pin, allowing usually the one device to accommodate different strengths of heat located at different miles from the Hall sensor. Band selection can either end up being hardwired or programmed electronically using an outside logic source such as a microcontroller.

The micropower Hall effect sensor switches coming from Diodes Incorporated are priced involving $0.17 USD and $0.20 USD each in 10k quantities.
