Allegro MicroSystems, LLC announces a new package offering for the two-wire, zero speed differential wheel speed sensor IC
2018-01-30 | ReturnThe single integrated circuit and magnet combination incorporates a dual element Hall-effect sensor IC and signal processing circuitry that switches in response to differential magnetic signals created by a rotating ferromagnetic target. The device contains a sophisticated compensating circuit to eliminate magnetic and system offsets. Digital tracking of the analogue signal is used to achieve true zero-speed operation. Advanced calibration algorithms are used to adjust the device gain and offset at power-up, resulting in air gap independent switchpoints, which greatly improves output accuracy and mitigates the effect of system anomalies such as target vibration and sudden changes in air gap. The regulated current output is configured for two-wire operation.
The ATS688LSN is provided in a lead (Pb) free 3-pin back-biased SIP package (suffix SN) with tin leadframe plating.
