Application Note
Improved Speed and Direction Sensing Using Vertical Hall Technology
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.
Application Note
Digital Position Sensor ICs—Continuous-Time to Chopper-Stabilized Cross-Reference Guide
This application guide will outline the differences between the two sensor types and provide system designers with the tools needed in order to select the appropriate sensor for their system.
Application Note
Ring Magnet Speed Sensing for Electronic Power Steering
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.
Application Note
Air-Gap-Independent Speed and Direction Sensing Using the Allegro A1262
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.
