Added Value of Using TMF8801
Benefits
Small footprint fits in the mobile phone bezel
Detecting central closest objects
Within 5 % of measurement (accuracy); no
multipath and no multiple object problems as
for iToF
Better accuracy detects reliably closest object
Minimum distance 20 mm
Maximum distance 2500 mm
No complex calibration
Compensates for dirt on glass
Class 1 Eye Safe
Features
Modular package - 2.2 mm x 3.6 mm x 1.0 mm
21º FOI
Time-to-Digital Converter (TDC)
Direct Time-of-Flight Measurement
Single Photon Avalanche Photodiode (SPAD)
Histogram based architecture
Dynamic cover glass calibration
Reliable Operation under demanding use cases
Fast VCSEL driver with protection

Applications
Distance measurement for camera autofocus
(Laser Detect Autofocus - LDAF)
Supporting low-power system operation by
enabling high-power components (i.e. 3D
camera) only when an object is in the
detection range
Collision avoidance
Presence detection - Object detection
