A1699

Two-Wire, Differential, Vibration-Resistant

Sensor IC with Speed and Direction Output

FEATURES AND BENEFITS

DESCRIPTION

• Integrated IC and capacitor, single overmolded package

to reduce external EMI-protection requirements

• Two-wire, pulse-width output protocol

• Highly configurable output protocol options

• Digital output representing target profile

• Speed and direction information of target

• Vibration tolerance

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.

TheICemployspatentedalgorithmsforthespecialoperational

requirements of automotive transmission applications. The

speed and direction of the target are communicated through a

variablepulse-widthoutputprotocol.TheA1699isparticularly

adept at handling vibration without sacrificing maximum air

gapcapabilityorcreatinganyerroneousdirectioninformation.

Theadvancedvibrationdetectionalgorithmwillsystematically

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.

□ Small-signal lockout for small amplitude vibration

□ Proprietary vibration detection algorithms for large

amplitude vibration

• Air-gap-independent switchpoints

• Large operating air gap capability

• Undervoltage lockout

• True zero-speed operation

• Wide operating voltage range

• AEC-Q100 automotive qualified

• Robust test-coverage capability with Scan Path and

IDDQ measurement

Advanced signal processing and innovative algorithms make

the A1699 an ideal solution for a wide range of speed- and

direction-sensing needs.

Package: 2-Pin SIP (Suffix UB)

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.
