ATS616LSG

The ATS616 gear-tooth sensor is a peak-detecting device that uses automatic gain

control and an integrated capacitor to provide extremely accurate gear edge detec-

tion down to low operating speeds. Each sensor module consists of a high-tem-

perature plastic shell that holds together a samarium-cobalt magnet, a pole piece,

and a differential open-collector Hall IC that has been optimized to the magnetic

circuit. This small package can be easily assembled and used in conjunction with a

wide variety of gear shapes and sizes.

The gear-sensing technology used for this sensor module is Hall-effect based. The

sensor incorporates a dual-element Hall IC that switches in response to differential

magnetic signals created by ferrous targets. The sophisticated processing circuitry

contains an A-to-D converter that self-calibrates (normalizes) the internal gain

of the device to minimize the effect of air-gap variations. The patented peak-

detecting filter circuit eliminates magnet and system offsets and has the ability to

discriminate relatively fast changes such as those caused by tilt, gear wobble, and

eccentricities. This easy-to-integrate solution provides first-tooth detection and

stable operation to extremely low rpm. The ATS616 can be used as a replacement

for the ATS612LSB, eliminating the external peak-holding capacitor needed by

the ATS612LSB.

The ATS616 is ideal for use in systems that gather speed, position, and timing

information using gear-tooth-based configurations. This device is particularly

suited to those applications that require extremely accurate duty cycle control or

accurate edge-detection, such as automotive camshaft sensing.

TheATS616 is provided in a 4-pin SIP that is Pb (lead) free, with a 100% matte

tin plated leadframe.
