TI DRV5056A2EDBZRQ1

The DRV5056-Q1 device is a linear Hall-effect sensor that provides a proportional response to the magnetic flux density of the south magnetic pole. This device can be used for precise position detection and has a wide range of applications. This analog output features a unipolar magnetic response, driving a voltage of 0.6V when there is no magnetic field and increasing the voltage in the presence of a south magnetic pole. For applications that sense a single magnetic pole, this response maximizes the output dynamic range. Four sensitivity options can further maximize the output swing based on the required sensing range. The device is powered by a 3.3V or 5V supply. It can sense the magnetic flux perpendicular to the top of the package, and two package options provide different sensing directions. The device uses a ratiometric architecture, which minimizes the errors caused by VCC tolerances when an external analog-to-digital converter (ADC) uses the same VCC for reference. Additionally, the device has a magnet temperature compensation function that cancels out magnet drift and achieves linear characteristics over a wide temperature range of -40°C to +150°C.
