D atas h e e t TRACKER™ NSE-5310 Position Sensor and Evaluation Pack 1 General Description 2 Key Features Smallest Size: Chip-scale packaging as small as 3.9 x 2.5 mm The TRACKER™ NSE-5310 position sensor is a magnetic sensor array with integrated on-chip digital encoding. With smallest size, 0.5µm resolution and low sensitivity to external magnetic fields, this miniature position sensor is a robust and cost-effective solution for precision positioning. Accurate, Non-contact Sensing: 0.5µm resolution, < 2µm repeatability Complete System on a Chip: Sensing and encoding integrated in one ingeniously small package On-chip encoding provides direct digital output using standard I²C protocol, eliminating the need for external pulse counters. Efficient control system communications allows up to two TRACKER NSE5310 position sensors for a single I²C bus. Direct Digital Output (I²C): Eliminates need for external pulse counters Robust: Insensitive to light, shock, vibration and particulates; less stringent mounting alignment The highest-resolution magnetic encoder available, the TRACKER NSE-5310 position sensor is insensitive to light, shock, vibration, and high-particulate environments. Absolute Performance: Zero reference, automatic gain & offset correction 3 Applications The TRACKER NSE-5310 position sensor is ideal for optical and imaging applications, such as focus and optical image stabilization as well as applications in consumer electronics, precision biomedical devices, industrial instrumentation and defense/security. Its small size makes it perfect for creating tiny, integrated closed-loop motion systems using micro motors, such as New Scale’s SQUIGGLE® motor. Figure 1.

The TRK-1T02-E evaluation pack includes a TRACKER NSE-5310 mounted in a TSSOP 20 package with flex cable and a suitable linear magnetic strip, a MC-31MB interface card and New Scale Pathway™ software to facilitate evaluation. The system can be connected to your computer using a USB interface providing direct position information to your application. TRACKER NSE-5310 in TSSOP or dice-on-foil packaging is available. Custom TRACKER NSE-5310 packaging such as wafer-level chip scale packaging and chip-on-board packaging can also be provided for qualified OEMs. Minimum order quantities may apply. TRACKER NSE-5310 - Mounted TSSOP 24 Magnet with alternate N-S pole pairs TRACKER NSE-5310 with Magnet Sensor array with on-chip encoder (SOIC) TRK-1T02-E evaluation pack includes a TRACKER NSE-5310 in a TSSOP 20 package on a board for ease of handling, along with a matching linear magnetic strip. See page 3 for details. www.austriamicrosystems.com Revision 0.1 2-4 TRACKER™ NSE-5310 Datasheet - F u n c t i o n a l D e s c r i p t i o n 6 Functional Description Moving a multi-pole magnetic strip over the Hall array on the encoder chip generates internal sinusoidal (SIN) and phase-shifted sinusoidal (COS) signals. These signals are filtered and transformed into angle (ANG) and magnitude (MAG), representing the absolute linear position of a 2mm long pole pair on the magnetic strip. Position information is read via I²C interface (SDA, SCL). Automatic gain control (AGC) adjusts for DC bias in the magnetic field and provides a large magnetic field dynamic range, for high immunity to external magnetic fields. It also provides an absolute magnitude of the magnetic field intensity, which is used to detect the end of the magnetic strip and thereby serves as a built-in zero reference. The TRK-1T02-E Evaluation Pack is a full- featured development platform for the TRACKER NSE-5310 Position Sensor. The MC-31MB interface card accepts the I²C input from one or two TRACKER NSE-5310 sensors, and connects via USB to your PC. Use the New Scale Pathway™ Software to view and collect position information. This development kit provides for easy sensor evaluation and system development.
