Current Sensors Procurement Notes

This specific part number is officially listed as obsolete or discontinued by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market suppliers. Ensure that any sourced units are genuine components with valid traceability documentation. Due to the end-of-life status, long-term supply continuity cannot be guaranteed through standard manufacturing channels. Evaluate alternative replacement options if future production volume is required.

Current Sensors Selection Notes

Select this component when a digital I2C interface is preferred over analog outputs for current sensing. The 16A rating suits moderate power applications requiring high precision. Consider the 24-pin QSOP footprint for PCB layout constraints. Verify compatibility with the host microcontroller's I2C bus voltage levels. The wide operating temperature range supports harsh environment deployments.

Current Sensors Part Context

The ACS764 series represents Allegro MicroSystems' family of fully integrated Hall-effect current sensors. These devices combine magnetic sensing elements with signal conditioning circuitry on a single silicon die. The XLFTR suffix indicates a tape-and-reel packaging format, while the 16AU designation specifies the 16A current rating and unidirectional operation mode within the product lineup.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers: ACS764XLFTR-32AU-T (for higher current capacity). No other direct pin-to-pin replacements are documented in official sources.
