Melexis, a company specializing in linear hall sensors, has introduced its third product generation. The new Melexis programmable linear Hall ICs, developed by Melexis, are surface-mount devices (SMD) that supports the demand for enhanced manufacturability of sensor modules and assemblies.
The new product does away with the traditional single-in-line approach as it needs a vigilant planned design consideration to avoid penalties for cost, reliability, EMI, space, mounting at the system level.
The SMD approach could be implemented in a number of position sensing applications, especially for short stroke linear motion where it could be integrated with a proper magnetic circuit and magnet thermal compensation.
According to Vincent Hiligsmann who works as Product Line Manager at Melexis, market surveys and preliminary feedback have clearly revealed that there are numerous automotive and industrial applications waiting for a highly accurate and economical programmable linear hall sensor in SMD package without the costs involved in a Melexis Triaxis solution. He further stated that the third generation of programmable linear Hall sensor ICs fulfills these requirements.
Melexis introduced a range of three programmable linear Hall sensors, the MLX90291 with 125 Hz PWM output, the MLX90288 with ratiometric analog output and the MLX90292 with a 2-wire PSI-5 protocol and a 2 kHz PWM mode. Sampling is available for all the three devices. In the future, three more products would join these devices.
