ATS699LSN

Two-Wire, Differential, Vibration-Resistant Sensor IC

with Speed and Direction Output

FEATURES AND BENEFITS

DESCRIPTION

• Integrated capacitor reduces requirements for external

EMI-protection components

• Two-wire, pulse-width output protocol

• Highly configurable output protocol options

• Speed and direction information of target

• Vibration tolerance

TheATS699LSN is an optimized Hall-effect integrated circuit

(IC) and rare-earth pellet combination that provides a user-

friendly solution for direction detection and true zero-speed,

digital gear-tooth sensing. The small package can be easily

assembled and used in conjunction with a wide variety of

gear-tooth-sensing applications.

□ Small signal lockout for small amplitude vibration

□ Proprietary vibration detection algorithms for large

amplitude vibration

TheICemployspatentedalgorithmsforthespecialoperational

requirements of automotive transmission applications. The

speed and direction of the target are communicated through a

variablepulse-widthoutputprotocol.TheATS699isparticularly

adept at handling vibration without sacrificing maximum air

gap capability or creating any erroneous “direction” pulses.

Even higher angular vibration caused by engine cranking is

completely rejected by the device. The advanced vibration

detection algorithm will systematically calibrate the sensor IC

on the initial teeth of true target rotation and not on vibration,

always guaranteeing an accurate signal in running mode.

• Air-gap-independent switchpoints

• Undervoltage lockout

• True zero-speed operation

• Wide operating voltage range

• Single chip sensing IC for high reliability

• Robust test-coverage capability with Scan Path and

IDDQ measurement

• Integrated back-biasing magnet

Advanced signal processing and innovative algorithms make

the ATS699 an ideal solution for a wide range of speed and

direction-sensing needs.

PACKAGE: 3-pin SIP (suffix SN)

This device is available in a lead (Pb) free 3-pin SIP package

with tin-plated leadframe.
