ATS601LSG Single Element, Tooth Detecting Speed Sensor IC Description Features and Benefits The ATS601LSG is a unique addition to the Allegro camshaft Digital output representing target profile sensor IC family of products. As a single element, defined Single Hall element for twistinsensitive mounting and poweron state, sensor IC, it provides first falling edge detection, direction insensitive polarity high running mode edge accuracy, and direction/orientation True zerospeed operation insensitivity over the full operating range of air gap, speed, Defined power-on state and temperature. The ATS601LSG consists of an optimized Air gap independent switchpoints Hall IC and a simple magnetic pellet configuration. Chopper stabilized Operation down to 3.3 V The single element Hall IC and magnetic pellet configuration Factory programmable options: switches in response to magnetic signals created by a Output polarity: low or high opposite tooth ferromagnetic target. The IC contains a low bandwidth filter Startup hysteresis: 40 G or 80 G that increases the noise immunity and the signaltonoise ratio Threshold location: 30% or 50% from signal peak of the sensor IC. Sophisticated digital circuit design eliminates Threshold update: single tooth (continuous) or four the detrimental effects of target geometry discontinuity, magnet tooth memory and system offsets, and thermal gradients. Signal processing Fully synchronous digital logic with Scan Path and IDDQ is used to provide zero speed performance independent of air testing gap and also to dynamically adapt device performance to the typical operating conditions found in automotive applications, Package: 4pin SIP (suffix SG) particularly camshaft sensing. The resulting output of the device is a digital representation of the ferromagnetic target profile. A number of factory programmable options allow for performance optimization to meet specific application Not to scale requirements. The ATS601 is provided in a 4pin SIP package (suffix SG) that is lead (Pb) free, with 100% matte tin leadframe plating.
