Version 1.10 |20 June 2017 PMW3901MB-TXQT: Optical Motion Tracking Chip Product Datasheet General Description The PMW3901MB-TXQT is PixArt Imaging's latest optical navigation chip designed with far field optics technology that enables navigation in the air. It is housed in a 28-pin chip-on-board (COB) package that provides X-Y motion information with a wide working range of 80 mm to infinity. It is most suitable for far field application for motion detection. Key Features  Wide working range from 80 mm to infinity  No lens focusing required during lens mounting process  Power consumption of < 9 mA @ run mode  16-bits motion data registers  Motion detect pin output  Internal oscillator – no clock input needed

Applications

 Devices that require far field motion detection, e.g Drone  Indoor and outdoor X-Y positioning especially in GPS denied environment Key Parameters Parameter Value Supply Voltage (V) VDD: 1.8 – 2.1 VDDIO: 1.8 – 3.6 Working Range (mm) 80 to infinity Interface 4-Wire SPI @ 2 MHz Package Type 28-pin COB Package with Lens Assembly: 6 x 6 x 2.28 mm

2.1 Absolute Maximum Ratings

Table 2. Absolute Maximum Ratings

Maximum Ratings are those values beyond which damage to the device may occur.
Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional

operation under absolute maximum-rated conditions is not implied.

Functional operation should be restricted to the Recommended Operating Conditions.
