Allegro’s ATS19580LSNx is one of the first to meet the stringent requirements of the transmission speed sensor market. This sensor is ideal for any 2-wire application requiring larger air gaps and stability over air gap, vibration, and thermal gradients. xMR designs are often dual-die solutions, but the ATS19580LSNx IC is a monolithic GMR IC integrating the GMR with the processing circuitry on a single die. The signal processing has advanced algorithms to compensate for the harsh environment seen when sensing gear tooth targets in transmissions, gear boxes, and other gear set type system designs. Gear interactions when shifting in transmission, for example, cause large dynamic air gap shifts. This has caused some sensors to flatline, requiring a sensor reset. The ATS19580LSNx has algorithms to handle these harsh movements without a flatline and reset condition. Vibration is often thought of as a zero-speed concern during operation. However, cold startup conditions can be some of the worst-case scenarios, making startup vibration as important as running mode stops. The ATS19580LSNx has a full tooth/valley vibration immunity at startup as well as in running mode operation. This guarantees robust operation and proper speed and direction communication over the entire operating range. The ATS19580LSNx is offered in the SN package. This package is well-known to most global automotive suppliers as a robust, easy to design-in solution. The SN is shipped in high volume with a proven reliability record.
