ATS668LSM Overview
Description
The ATS668LSM is an optimized Hall-effect integrated circuit (IC) and permanent magnet pellet combination with integrated EMC protection components to provide a user-friendly solution for true zero-speed digital gear tooth sensing. The small package can be easily assembled and used in conjunction with a wide variety of gear tooth sensing applications.
Key Features
- Three-wire back-biased speed sensor optimized for transmission speed-sensing applications
- Integrated in-package EMC protection circuit allows compliance to most automotive EMC environments without external circuitry
- Small-signal lockout for immunity to vibration
- Tight timing accuracy over full operating temperature range
- True zero-speed operation
- Air gap independent switch points
- Large operating air gaps achieved through use of gain and offset adjust circuitry
- Wide operating voltage range with undervoltage lockout (UVLO)
- Digital output representing target profile
- Single-chip sensing IC for high reliability
