Introduction

The TMF8820, TMF8821 & TMF8828 are a family of direct time-of-flight (dToF) sensors available in a small footprint modular package with integrated Vertical Cavity Surface Emitting Laser (VCSEL). The dToF device is based on SPAD, TDC and histogram technology and achieves 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3, 4x4, 3x6 and 8x8 multizone output data and a very wide, dynamically adjustable, field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8820/21/28 provide distance information together with confidence values on its I²C interface.

Applications

• Distance measurement for camera autofocus - Laser Detect Autofocus - LDAF (mobile phone)
• Presence detection (computing and communication)
• Object detection and collision avoidance (robotics)
• Light curtain (industrial)
