- With the use of this design, a user can create a compact and cost-effective RGB LED source for lighting applications
- The device consists of 16 RGB LEDs which can make color combinations of up to 10,000 different shades
This reference design enables a human-machine interface using a LED ring. It utilizes two LP5024 LED drivers which creates vivid lighting patterns. The design helps to resolve common challenges for end equipment with complicated lighting patterns. These devices usually work on a constant voltage supply.
10000 color combinations
According to the design, the driver works for a voltage ranging from 3 Volt up to 5.5 Volt. It can produce an output current of up to eight milliamperes per channel. The device consists of 16 RGB LEDs which can make color combinations of up to 10,000 different shades.
LP5024 can produce up to seven different lighting patterns. It also provides an analogue dimming control range from 0 up to 100 per cent. Using this analogue dimming, the intensity of the LED’s can be altered at any given point of time.
Supports I2C protocols for programming
This reference design uses two RGB LED drivers. These drivers consist of 24 different channels. It has a 12-bit data bus and works on a low quiescent current. The device can be programmed and interfaced through an I2C communication protocol. It improves user experience in accessing features like color mixing and brightness controlling.
The optimized performance for RGB LEDs makes the LP5024 an excellent fit for human-machine interaction applications. It is also equipped with an OPT3001 sensor. This sensor provides dynamic sensing for ambient light. Additionally, the device contains a launchpad. The MSP432P401R LaunchPad sends a control signal to adjust the analogue current of LP5024 and various lighting patterns.
