ATS19200: High-Accuracy Hall-Effect Wheel Speed Gear Tooth Sensor IC

The ATS19200 is an optimized Hall-effect integrated circuit (IC), rare-earth pellet, and high-temperature ceramic capacitor in a single over-molded package that reduces size while improving EMC robustness. No external PCB or capacitor is required.

The ATS19200 offers integrated diagnostics and certified safety design process.

The device provides a user-friendly solution for true zero-speed digital gear tooth sensing in two-wire applications, such as automotive wheel speed, as well as motorcycle/moped anti-lock braking systems. The ATS19200 can also be used as a general purpose speed sensor in recreational vehicles (mopeds, snowmobiles, four-wheelers) and industrial equipment (forklifts, tractors and agricultural equipment).

The ATS19200 is provided in a lead (Pb) free 3-pin back-biased SIP package (suffix SN) with tin leadframe plating.

ATS19200 was developed in accordance with ISO 26262:2011 as a hardware safety element out of context with ASIL B capability for use in automotive safety-related systems when integrated and used in the manner prescribed in the applicable safety manual and datasheet.
