The PAT9125EL-TKIT from PixArt Imaging Inc. is a low-power optical tracking miniature chip designed for precise motion detection using laser-based optical navigation technology. It integrates both the optical sensor and VCSEL laser light source into a single compact package, enabling accurate tracking even on smooth or glossy surfaces. This device captures sequential surface images and processes them internally to determine movement direction, speed, and displacement (X/Y data), which can be accessed by a host controller via digital interfaces. It is particularly suited for space-constrained, battery-powered, and enclosed systems, eliminating the need for mechanical components like code wheels or special surface markings. Key Features Integrated optical sensor + VCSEL laser (850 nm) in a single package No external lens required, simplifying design Wide depth of field (DOF): 1–30 mm, even on reflective surfaces Programmable resolution up to ~1275 CPI Supports I²C (TKIT) interface (SPI variant available as TKMT) Motion detection interrupt output Built-in oscillator (no external clock needed) Low power consumption: Run: ~0.7 mA Sleep: down to 10 µA Power-down: ~5 µA Pre-calibrated laser (no calibration required) IEC/EN 60825-1 Class 1 eye-safe laser compliant Key Specifications Supply Voltage: VDD: 1.7–3.6 V VLD (laser): 2.7–3.6 V Max Tracking Speed: up to ~30 inches/sec Package: 8-pin LGA (3.5 × 3.2 × 1.0 mm) Interface: I²C (for TKIT variant)
