ATS627LSG

ATS627LSG True Zero Speed, Low Jitter, High Accuracy Position Sensor IC 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 Undervoltage lockout 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 Package: 4-pin SIP (suffix SG) Not to scale Description TheATS627 is a true zero-speed gear tooth sensor IC consisting 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. The dual-element Hall IC switches in response to differential magnetic signals created by a ferrous target. Digital processing 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. 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 magnet...
