ATS694LSM
Overview
The ATS694LSM is a combined Hall-effect sensing integrated circuit, back-biasing rare-earth pellet, and EMC protection circuit that provides a user-friendly, PCB-less solution for true zero-speed digital crankshaft sensing. The ATS694 provides speed and direction information through a variable pulse-width output protocol.
- Allegro SM package with integrated EMC components provides robustness to most automotive EMC requirements
- Integrated back-biasing rare-earth pellet
- Digital output with speed and direction information provides ferromagnetic target position information
- Enhanced algorithms provide low jitter and high output accuracy performance
- Electrical offset compensation through chopper stabilization
- Dual zero-crossing with internal hysteresis
- Highly repeatable across operating temperature range
- Automatic Gain Control and Automatic Offset Adjust circuits result in air-gap-independent switch points
- Robust test coverage capability using Scan Path and IDDQ measurement
- Factory-programmable options for application-specific performance optimization PACKAGE: 3-pin SIP (suffix SM) Not to scale
