追求安全？我们的所有开关和闩锁现在都按照 ISO 26262 标准进行开发。
Our high-performance magnetic latches offer you industry-leading jitter performance, EMC/ESD robustness, and magnetic precision—all at competitive price points.
Vertical Hall Technology by Allegro (VHT) sensing solutions revolutionize motors and encoders, delivering quadrature signals independent of magnet pitch or air gap.
OEMs and tier one providers choose from our broad portfolio of Hall-effect switches for applications like seat belt buckles, seat track, shift selectors, door ajar, and so much more.
Perfect for sensing absolute position or proximity in harsh automotive environments, our three-wire switches are ideal for applications like shift selectors, door ajar, user interfaces and vane-interrupt systems.
Extend the life of your battery-powered devices with these integrated Hall-effect sensor ICs. These switches offer low power consumption and are ideal for use in on/off switching applications and for detection of tampering in utility meters.
Don't see the right solution? Take a look at products we've developed for very specific applications. We offer deep and broad applications expertise to help you find—or create—a device that fits your needs.
The A1262 2D dual-channel Hall-effect sensor IC is offered in a 5-pin SOT23W surface-mount package, as well as a 4-pin SIP through-hole package. It features operation with traditional planar—as well as vertical—magnetic field direction.了解更多
The A1262 integrated circuit is an ultrasensitive dual-channel Hall-effect latch. As with conventional dual-channel latches, the quadrature outputs of the A1262 indicate rotation direction and position/speed of a rotating ring magnet target.了解更多
This application note assumes the user is programming an Allegro fully integrated back biased Hall effect switch or that the user has designed an appropriate magnetic circuit to accommodate the programming range of a programmable unipolar Hall effect switch.了解更多
Proper control of Electric Power Steering (EPS) systems requires both speed and direction information from the steering input shaft. This control will typically come from both high-resolution speed information and fairly coarse position information.了解更多
There are four general categories of Hall-effect IC devices that provide a digital output: unipolar switches, bipolar switches, omnipolar switches, and latches. Latching Hall-effect sensor ICs, often referred to as "latches," are digital output Hall-effect switches that latch output states.了解更多
AN296233 - Electrical interfaces for active sensor integrated circuits (ICs) include both two-wire and three-wire interfaces. These two technology styles are named for the number of required connections needed to communicate the sensor output. This application note discusses use and tradeoffs of ...了解更多
AN296238 - In this applicate note, we discuss the use of the APS13568, an integrated circuit that combines an ultra-sensitive, omnipolar, micropower Hall-effect switch with a linear programmable current regulator which can provide up to 150 mA current to drive high brightness LEDs.了解更多
