ELM53103GDT has been revolutionizing the design of LED applications when it comes to Circuit Board Indicators, Arrays, Light Bars, Bar Graphs. It is a robust LED display module that consists of three LED arrays (driven by the ELM5306 LED driver), seven LED current sink bar graphs, and one LED current source bar graph, connected to the microcontroller. The ELM53103GDT is designed to be used in 1.2V and 3.3V applications, and its simple to use design is compatible with industry leading microcontrollers.

The working principle of ELM53103GDT is based on the current sink/source driven LED display principle. It uses ELM5306 LED drivers to achieve high level current sink or source driving, or both. Through the input and output of the LED driver, five-level drive current up to 20mA is realized. The logic voltage of the ELM53103GDT can be adjusted to 1.2V or 3.3V. It can be used in 2.7-3.6V, 2.7-5.5V power supply voltage range. During operation, compatible microcontrollers will supply the logic voltage to the ELM53103GDT, and then the ELM53103GDT will drive the current of the LED display via the resistors. When the current increases, the brightness of the LED display will increase, and vice versa.

The ELM53103GDT is applicable to a variety of Circuit Board Indicators, Arrays, Light Bars, Bar Graphs designs. It is specifically used for applications that require multiple LEDs such as LCD backlighting, safety boards and advertising displays. With the ELM53103GDT module, more LEDs can be driven from the microcontroller in a compact and efficient manner. The ELM53103GDT is designed for multi-condition displays, such as dimming, lighting, time display, voltage display, etc. It is also applicable to car instruments, display instrument panels, or instrument dashboard display.In addition, the ELM53103GDT is also applicable to bar graph displays. Its bar graph display can be used to indicate temperature changes, pressure changes, level changes or other types of changes with the most intuitive light bar display.

Overall, ELM53103GDT is a widely applicable LED with multiple current source/sink capabilities. It is widely used in LCD backlighting, safety boards, display instrument panels, instrument dashboard displays, car instruments and other Circuit Board Indicators, Arrays, Light Bars, Bar Graphs design applications. With its simple to use design, it offers industry leading microcontrollers a high level of LED driving.
