ATS627LSG

True Zero Speed, Low Jitter, High Accuracy

Position Sensor IC

Description

Features and Benefits

• Highly accurate in presence of:

▫ Anomalous target geometry (tooth-tooth variation)

▫ Signature teeth or valleys

▫ Target runout

• Highly repeatable output edges (low jitter)

• True zero-speed operation

TheATS627isatruezero-speedgeartoothsensorICconsisting

of an optimized Hall IC and rare earth pellet configuration in

a single overmolded package. The integrated circuit provides

a manufacturer-friendly solution for digital gear tooth sensing

applications. This small package can be easily assembled and

used in conjunction with gears of various shapes and sizes.

• Undervoltage lockout

The dual-element Hall IC switches in response to differential

magneticsignalscreatedbyaferroustarget. Digitalprocessing

of the analog signal provides zero-speed performance

independent of air gap as well as dynamic adaptation of

device performance to the typical operating conditions found

in automotive applications.

• Air gap independent switchpoints

• Defined power-on state

• High operating temperature

• Single-chip sensing IC for high reliability

• Enhanced quality through Scan Path and IDDQ

measurement

• Enhanced EMC performance

High-resolution peak detecting DACs are used to set the

adaptive switching thresholds of the device. Bounded tracking

and switchpoint hysteresis reduce the negative effects of any

anomalies in the magnetic signal associated with the targets

used in many automotive applications. This sensor IC system

is optimized for engine crank applications that utilize targets

that possess signature regions.

Package: 4-pin SIP (suffix SG)

Not to scale

This device is available in a lead (Pb) free 4-pin SIP package

(SG) with a 100% matte tin plated leadframe.
