Allegro MicroSystems, LLC announces a new linear hall IC targeted at the automotive and industrial markets. New applications for linear output Hall-effect sensor ICs, such as displacement and angular position, require higher accuracy and smaller package sizes. Allegro’s ALS31000 linear Hall-effect sensor IC has been designed specifically to meet both requirements.

The accuracy of this device is enhanced via end-of-line optimization. The ALS31000 features non-volatile memory to optimize device sensitivity and the quiescent voltage output (QVO: output in the absence of a magnetic field) for a given application or circuit. Optimized performance is sustained across the full operating temperature range by programming the temperature coefficient for both sensitivity and QVO at Allegro end-of-line test.

This ratiometric Hall-effect sensor IC provides a voltage output proportional to the applied magnetic field. The quiescent voltage output is adjusted to around 0.7 V and the output sensitivity is set to 2.4 mV/G. The features of this linear device make it ideal for use in automotive and industrial applications requiring high accuracy and operation across an extended temperature range, –40°C to 150°C. Each BiCMOS monolithic circuit integrates: a Hall element, temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the Hall element, a small-signal high-gain amplifier, a clamped low-impedance output stage, and a proprietary dynamic offset cancellation technique.

Allegro’s ALS31000 sensor IC family is offered in the LH package style: a SOT-23W style, miniature, low-profile package for surface-mount applications. The package is lead (Pb) free, with 100% matte-tin leadframe plating.
