Linear Hall Sensor

Moving away from the conventional single-in-line package (SIP) approach, which requires more careful design consideration to avoid mounting, space, EMI, reliability and cost penalties at the system level in many applications, Melexis programmable linear Hall ICs are surface-mount devices (SMD) supporting the trend for improved manufacturability of sensor assemblies and modules. Of the three devices in the family the MLX90288 features ratiometric analog output, whereas the MLX90291 comes with a 125 Hz PWM output. Both parts are housed in an SOIC-8 SMD package with identical pinout. Available in a dual die redundant TSSOP-16 package, the MLX90292 is released to the market targeting high reliability applications, It reports a digital telegram using the fast and safe 2-wire PSI-5 protocol, which includes a temperature output next to the magnetic flux density. It also features 2 kHz PWM mode. All three devices are readily available together with the appropriate PTC-04 programming tools. They can be implemented for numerous position sensing applications. Specifically for short stroke linear motion, when combined with an appropriate magnetic circuit and adequate magnet thermal compensation.
