Matrix produces a wide range of Hall-sensing solutions for applications including automotive, smart home, consumer electronics, robotics, and test and measurement, whether that be in the form of a Hall element, switching Hall IC, linear Hall IC, or an integrated sensor. These devices are available in a wide variety of package options with the World’s smallest Hall sensor (used in camera modules) a key highlight in the range.
The use of novel materials gives Matrix’s Hall elements greatly improved sensitivity over traditional silicon-based alternatives:
The gallium arsenide (GaAs) devices offer 1-order-of-magnitude sensitivity improvements over silicon with extremely low drift with temperature (approx. 0.3%/°C max. for input resistance), high signal-to-noise ratio, and a linear dynamic range up to 2 T with zero hysteresis. An example datasheet for a product in this family of devices can be found here.
The indium antimonide (InSb) devices further improve sensitivity to 2 orders of magnitude over silicon at the expense of sensitivity to changes in temperature (approx. -1.8%/°C for input resistance). These solutions are best suited for closed-loop current sensing and motor rotor position control.
Both types of devices feature operating temperatures as wide as -40°C to +125°C with various Hall voltage options (10s to 100s of mV), resistance characteristics (100s to 1000s of Ω), and maximum input currents up to 25 A for GaAs and 20 A for InSb.
Evaluation boards are available on request for this technology, and Matrix states minimum order quantities from 500 pieces to 10,000 pieces depending on the device selected (Hall elements).
