The OPT3001-Q1 is an optical sensor that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye and includes significant infrared rejection.

The OPT3001-Q1 is a single-chip lux meter, measuring the intensity of light as visible by the human eye. The precision spectral response and strong IR rejection of the device enables the OPT3001-Q1 device to accurately measure the intensity of light as seen by the human eye, regardless of light source. The strong IR rejection also aids in maintaining high accuracy when industrial design calls for mounting the sensor under dark glass for aesthetics. The OPT3001-Q1 device is designed for systems that create light-based experiences for humans, and an ideal preferred replacement for photodiodes, photoresistors, or other ambient light sensors with less human eye matching and IR rejection.

The digital operation is flexible for system integration. Measurements can be either continuous or single-shot. The control and interrupt system features autonomous operation, allowing the processor to sleep while the sensor searches for appropriate wake-up events to report through the interrupt pin. The digital output is reported over an I2C- and SMBus-compatible, two-wire serial interface.

The low-power consumption and low-power supply voltage capability of the OPT3001-Q1 device enhance the battery life of battery-powered systems.

Measurements can be made from 0.01lux up to 83klux, without manually selecting full-scale ranges, by using the built-in, full-scale setting feature. This capability allows light measurement over a 23-bit effective dynamic range.

TIDA-01500 — 用於 HVAC HMI 的車用多通道 LED 驅動器參考設計

在 HVAC(暖氣、通風與空調)人機介面 (HMI) 中,顯示器與按鈕通常會使用大量 LED 進行照明。這些 LED 的驅動電路傳統上是以分離式方式實現,也就是由微控制器 (MCU) 驅動外部低壓側 BJT,使其對 LED 進行電流下拉,電流則由串聯電阻進行限制。這些 BJT 可以透過 PWM 訊號驅動,以實現調光效果,或單純作為開關使用。本參考設計提供一種具成本效益的替代 LED 驅動器解決方案,能夠驅動多個 LED,且無需使用限流電阻器。此參考設計允許設計人員針對每個二極體單獨調整電流與 PWM 調光訊號,但以串聯方式連接至同一個接腳的情況除外。
