ATS627LSGTN-MN-T

• Product introduction

The ATS627 is oneTrue zero speed gear tooth sensorICs, including optimized Hall IC and rare earth magnet configurations packaged in a single overmolded package. Integrated circuitry provides a manufacturer-friendly solution for digital gear tooth sensing applications. This small package is easy to assemble and can be used with gears of all shapes and sizes.

This dual-element Hall IC switches in response to differential magnetic signals generated by magnet targets. Digital processing of analog signals provides true zero-speed performance independent of air gap and dynamically adapts device performance to operating conditions common in automotive applications.

The high-resolution peak detection DAC is used to set the device's adaptive switching threshold. Limit tracking and switchpoint hysteresis reduce the adverse effects of any anomalies in the various magnetic signals associated with targets used in many automotive applications. The sensor IC system is optimized for crank applications utilizing targets with signal regions.

The device is available in a lead (Pb) 4-pin SIP package (SG) with 100% matte tin leadframe plating.
