LED indication is an important process in many technological fields, in which discrete indication is a major application. When displaying data in a discrete format, it is important to use a reliable and accurate signal source. The EAST3015GA1 is one of the most reliable signal sources available for discrete indication and can be used in a variety of applications. This article will discuss the application field and working principle of the EAST3015GA1.

Application Field

The EAST3015GA1 is a LED indicator integrated circuit that is designed to drive LED indicators with an input voltage range of 4.5 to 18V. With a maximum operating temperature of 60°C, the EAST3015GA1 is suitable for a wide range of applications and can be used in both industrial and consumer products. It is well-suited for being used in a number of different discrete indication applications for displays and indicators such as automotive, home appliances, industrial automation equipment, medical devices, office equipment, process control and telecommunications.

Working Principle

The EAST3015GA1 is a dual-channel LED indicator IC, which integrates two high-accuracy current mirrors, two voltage mirrors and two booster-type switch outputs. It is designed to drive two independent LED indicators with an operating temperature range of -25°C to 60°C. The two channels each have a separate input stage and output switch, with the two channels connected in parallel by two pins of the same voltage source. This allows the EAST3015GA1 to switch between two different voltages to drive the LEDs with higher accuracy.

The two input stages within the EAST3015GA1 are designed to achieve precise current control and symmetrical regulation. The two input stages are connected to two pins, which then act as the input voltage source to each channel. The two voltage mirror circuits monitor the voltage of the input pins for proper current regulation and protection. Each mirror also provides precise current precision by controlling the current mirrors output current via an in-dither circuit. The output switches are then used to regulate the magnitude of the output current.

The EAST3015GA1 is a high-precision LED indicator integrated circuit that is designed for use in a variety of applications. It is well-suited for being used in a number of different LED indication applications for discrete indicators and displays due to its wide operating temperature range and precise current regulation. In addition, its two Booster-Type switch outputs provide precise current regulation, allowing for precise control of the LED indicators.
