Programmable Linear Hall Sensors feature surface-mount design.June 15, 2011 -
Model MLX90288 linear Hall sensors feature ratiometric analog output while MLX90291 units integrate 125 Hz PWM output; both are housed in SOIC-8 surface mount package. Available in dual die redundant TSSOP-16 package, MLX90292 models report digital telegram using 2-wire PSI-5 protocol, which includes temperature output next to magnetic flux density. They also have 2 kHz PWM mode. All 3 IC sensor models come with appropriate PTC-04 programming tools.

Melexis Reinvents the Programmable Linear Hall Sensor and Goes Surface-Mount
IEPER, Belgium - Melexis, the pioneer in programmable linear Hall sensors
launches its third product generation. This new family breaks with the conventional "single-in-line-package" (SIP) approach since they require more careful design consideration to avoid mounting, space, EMI, reliability and cost penalties at the system level. The new Melexis programmable linear Hall ICs are surface-mount devices (SMD) supporting the trend for improved manufacturability of sensor assemblies and modules.
The SMD approach gets applied for a single-die device family.
It 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.
Vincent Hiligsmann, Product Line Manager: "Our market surveys and initial feedback are clear: there are many industrial and automotive applications which were waiting for a state-of-the-art, high-accuracy and cost-effective programmable linear Hall sensor in surface-mount package but without any allowable premium for a Melexis Triaxis solution. The third generation of Melexis programmable linear Hall sensor ICs addresses those needs and brings the answer."
Addressing the trend Melexis today launches a series of three programmable linear Hall sensors. The MLX90288 featuring ratiometric analog output and the MLX90291 featuring 125 Hz PWM output, both parts in an SOIC-8 SMD package with identical pinout. Finally the MLX90292 is released to the market targeting high reliability applications, available in a dual die redundant TSSOP-16 package. This third sensor, the MLX90292, 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 features also 2 kHz PWM mode.
All three devices are readily available in sample and production quantities together with the appropriate PTC-04 programming tools.
In the coming months, the family will be extended by three more programmable products: the MLX91207 featuring analog output with best in class bandwidth for current sensing applications in an optimized SOIC-8 package, the MLX90290 in a TSOT-3L package (analog output) and the MLX90293 with the emerging SENT output protocol.
The extended product family of Melexis, including both the Triaxis Position Sensor family and the newly released SMD Linear Hall Sensors, will enable the company to support a broad range of applications in automotive markets and beyond.
