Allegro MicroSystems, Inc. has introduced the smallestA332303D sine/cosine hall-effect position sensor IC which contains two discrete analog signal paths for superior high-speed performance and offers system designers a cost-effective solution for automotive and industrial applications. This new sensor IC with a tiny SOT23-W package size can also be used as an angle sensor and is ideally suited for high-speed, low-latency motor position applications including brushless DC motors, AC synchronous permanent magnet, and asynchronous inductive motors.
The A33230 sensor IC 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 angles in any plane (XY, XZ, or YZ) while providing independent sine and cosine outputs.
