DESCRIPTION
The A1699 is an optimized Hall-effect integrated circuit (IC)
that provides a user-friendly solution for direction detection
and true zero-speed, digital ring-magnet sensing. The small
package can be easily assembled and used in conjunction with
a wide variety of target sensing applications.
The IC employs patented algorithms for the special operational
requirements of automotive transmission applications. The
speed and direction of the target are communicated through a
variable pulse-width output protocol. TheA1699 is particularly
adept at handling vibration without sacrificing maximum air
gap capability or creating any erroneous direction information.
The advanced vibration detection algorithm will systematically
calibrate the sensor IC on the initial magnetic poles of true
target rotation and not on vibration, always guaranteeing an
accurate signal in running mode.
Advanced signal processing and innovative algorithms make
the A1699 an ideal solution for a wide range of speed- and
direction-sensing needs.
The A1699 is provided in a 2-pin miniature SIP package
(suffix UB) that is lead (Pb) free, with tin leadframe plating.
The UB package includes an IC and capacitor integrated into a
single overmolded package to reduce external EMI protection
requirements.
