TMD37253
Overview
The TMD37253 is an integrated optical module containing a color (RGB) sensor, ambient light sensor (ALS), and a proximity detection system with a built-in IR LED. It operates over a narrow supply voltage range of 1.7V to 2.0V, making it specifically optimized for mobile and battery-powered electronics. The device includes UV/IR blocking filters and a 46-degree average field of view for accurate light sensing in diverse lighting environments.
Why Choose This Part
The module integrates the IR LED and sensor into a small 2mm x 3.65mm SMD package, reducing PCB footprint and simplifying optical mechanical design. It features ultra-low power consumption with a sleep current of only 5 uA and advanced power management states to extend battery life in portable devices.
Applications
Getting Started
Communication is handled via a standard I2C interface, allowing for easy integration with low-voltage microcontrollers. Developers should focus on calibrating the programmable gain and integration time settings to match the optical transmission characteristics of the final product housing or cover glass.
