ATS601: Single Element, Tooth Detecting Speed Sensor IC

The ATS601LSG is a unique addition to the Allegro™ camshaft sensor IC family of products. As a single element, defined power-on state, sensor IC, it provides first falling edge detection, high running mode edge accuracy, and direction/orientation insensitivity over the full operating range of air gap, speed, and temperature. The ATS601LSG consists of an optimized Hall IC and a simple magnetic pellet configuration.

The single element Hall IC and magnetic pellet configuration switches in response to magnetic signals created by a ferromagnetic target. The IC contains a low bandwidth filter that increases the noise immunity and the signal-to-noise ratio of the sensor IC. Sophisticated digital circuit design eliminates the detrimental effects of target geometry discontinuity, magnet and system offsets, and thermal gradients. Signal processing is used to provide zero speed performance independent of air gap and also to dynamically adapt device performance to the typical operating conditions found in automotive applications, 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 requirements.

The ATS601 is provided in a 4-pin SIP package (suffix SG) that is lead (Pb) free, with 100% matte tin leadframe plating.
