3D Hall-Effect Sensor with Sine/Cosine Outputs A33230LLHALT-XZ-S-AR-10
The A33230 is the world's smallest 3D sine/cosine sensor currently available in the market. It contains two discrete analog 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 is ideally suited for high-speed, low-latency motor position applications including brushless DC motors, and is an excellent choice for both AC synchronous permanent magnet and asynchronous inductive motors. It will easily "drop-in" to systems that are already set-up to receive sine/cosine sensor 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 angles in any plane (XY, XZ, or YZ), while providing independent sine and cosine outputs. It’s a cost-effective solution with a small footprint that makes it ideal for legacy applications where a designer needs to minimize PCB size, or is looking for an opportunity to reduce BOM cost in automotive and industrial applications such as factory robotics, windshield wipers, in-cabin motors and more.
