The A33230 contains two discrete analog signal paths for superior high-speed performance, and its tiny SOT23-W package size makes it ideal for situations where PCB space is limited. 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 both outputs.
The A33230 incorporates vertical, planar Hall effect elements with orthogonal sensing axes, providing a 90° phase separation that is inherently independent of the magnet pole separation and air gap. It comes pre-programmed to measure angles in any plane (XY, XZ, or YZ) while providing independent sine and cosine outputs.
“With the ability to detect fields in the X, Y, and Z planes, sine/cosine Hall effect sensors are reliable and proven options for many applications,” said Scott Milne, Director of the Position and Angle Sensors Business Unit at Allegro. “The introduction of the A33230 gives Allegro customers access to an expanded selection of position and angle sensors for industrial and automotive applications, such as factory robotics, windshield wipers, cabin motors, and more. It’s a cost-effective, compact solution that’s ideal for legacy applications where a designer needs to minimize PCB size or is looking for an opportunity to reduce bill of materials costs.”
Price and Availability
The A33230 is available in a 5-pin SOT23-W package (LH suffix). The package is RoHS compliant and lead-free (Pb), with a 100% matte tin plating.
