Allegro announces industry’s smallest sine/cosine 3D position sensor

Allegro MicroSystems, Inc., a global leader in sensing and power solutions for motion control and energy-efficient systems, today announced its new A33230 sine/cosine 3D Hall-effect position sensor IC. The A33230 is the smallest sine/cosine 3D sensor currently available in the market, and offers system designers a cost-effective solution for automotive and industrial applications with a quick time to market.

The A33230 contains two discrete analogue signal paths for superior high-speed performance, and the tiny SOT23-W package size makes it ideal for situations where PCB space is at a premium. The IC can also be used as an angle sensor, provided the system includes an electronic control unit (ECU) capable of performing CORDIC calculations on the two outputs.

The A33230 incorporates vertical and planar Hall-effect elements with sensing axes that are orthogonal to one another, providing 90° of phase separation, which is inherently independent of magnet pole spacing and air gap. It comes pre-programmed to measure angle in any plane (XY, XZ, or YZ) while providing independent sine and cosine outputs.
