1 / 21 page  NSE-5310 Miniature Position Encoder SOIC with Zero Reference and I²C Output www.austriamicrosystems.com Revision 1.0 1 - 21 Data Sheet 1 General Description The TRACKER NSE-5310 is an incremental position sensor with on- chip encoding for direct digital output. A Hall element array on the chip is used to derive the incremental position of an external magnetic strip placed above the IC at a distance of 0.3 mm (typ). This sensor array detects the ends of the magnetic strip to provide a zero reference point. The integration of Hall-effect position sensors, analog front end and digital signal processing on a single IC chip provides an ingeniously small position sensor, without the need for external pulse counters. Direct digital output is accessible over the serial interface using I²C protocol. The TRACKER NSE-5310 provides absolute position information over the length of a magnet pole pair (2 mm). A user can count pole pairs and achieve absolute position information over the entire length of the magnet (essentially unlimited). With better than 0.5 micron resolution, the TRACKER is a robust, cost-effective alternative to miniature optical encoders. It can be used as a linear or off-axis rotary encoder. Figure 1. TRACKER NSE-5310 Block Diagram 2 Key Features Direct digital output using I²C protocol End-of-magnet detection for built-in zero reference 0.488 μm resolution < 2 μm bi-directional repeatability < ±10 µm absolute error On-chip temperature sensor Magnetic field strength monitor Available in TSSOP or 3.9 mm x 2.5 mm die for chip-on-board mounting Custom packaging such as wafer-level chip scale packaging can be provided. Minimum order quantities may apply. RoHS compliant 3 Applications The NSE-5310 is ideal for Micro-actuator and servo drive feedback, Replacement for optical encoders, Optical and imaging systems, Consumer electronics, Precision biomedical devices, Instrumentation and automation, Automotive applications, and Integrated closed-loop motion systems using New Scale’s SQUIGGLE micro motor.
