ATS667 HIGH ACCURACY GEAR TOOTH SENSOR ICS
ATS667LSG: True Zero-Speed, High Accuracy Gear Tooth Sensor IC
The ATS667 is a true zero-speed gear tooth sensor IC consisting of an optimized Hall IC-rare earth pellet configuration in a single overmolded package. The unique IC and package design provides a user-friendly solution for digital gear tooth sensing applications. This small package can be assembled simply and used in conjunction with gears of various shapes and sizes.
The device incorporates a dual element Hall IC that switches in response to differential magnetic signals created by a ferromagnetic target. The IC contains a sophisticated compensating circuit designed to eliminate the detrimental effects of magnet and system offsets. Digital processing of the analog signal provides zero-speed performance independent of air gap and also dynamic adaptation of device performance to the typical operating conditions found in automotive applications (reduced vibration sensitivity). High-resolution peak detecting DACs are used to set the adaptive switching thresholds of the device. Hysteresis in the thresholds reduces the negative effects of any anomalies in the magnetic signal associated with the targets used in many automotive applications.
The ATS667 is optimized for transmission applications. It is available in a lead (Pb) free 4-pin SIP package with a 100% matte tin plated leadframe.
