DESCRIPTION

· The ATS19200 is a high-accuracy Hall-effect wheel speed gear tooth sensor IC, integrating a Hall-effect IC, rare-earth pellet, and high-temperature ceramic capacitor in a single overmolded package, eliminating the need for external EMC protection.

· It features a dual-element Hall-effect sensor IC and signal processing circuitry, switching in response to differential magnetic signals from a rotating ferromagnetic target.

· Advanced calibration algorithms adjust gain and offset at power-up, ensuring air gap-independent switchpoints and high accuracy for pitch and duty cycle.

· Integrated diagnostics detect IC failures, ensuring ASIL B(D) compliance, and built-in EEPROM provides device traceability throughout production.

FEATURES

· Integrated back-bias magnet simplifies design with ferromagnetic gear targets.

· Single overmolded package with integrated capacitor enhances EMC robustness.

· Advanced threshold switching algorithm ensures high accuracy over the operating air gap range.

· ASIL B(D) rating supported by integrated diagnostics and certified safety design process.

· EEPROM for device traceability throughout production.

· Two-wire current source output supporting speed and ASIL protocol.

APPLICATIONS

· True zero-speed digital gear tooth sensing in two-wire applications.

· Automotive braking systems.

· Two-wheeler braking systems.
