Overview

The LS A676-R1S1-1-Z is part of the family of discrete LEDs available from LSI. It is a single color indicator device that uses a LEDs as a visible output device. The main application field of this discrete LED is to provide an indication of system status; typically to indicate when the system is on, off, working, or in error. The LS A676-R1S1-1-Z is suitable for a range of applications from automotive electronics and industrial sectors to consumer goods and household appliances.

Design and Construction

The LS A676-R1S1-1-Z is a discrete LED device comprising of an LED assembly and driver circuitry in a standard six-pin plastic package. The LED is size SMT0805 and is available in a variety of different colors, such as green, red, blue and yellow. The LED has a maximum forward current rating of 20mA, maximum reverse voltage of 2V, typical luminous intensity of 2.0cd and viewing angle of 15°. The LED is driven by the integrated driver circuit, which consists of an SCR gate, and a reverse polarized protection diode across the LED. The integrated circuit can drive the LED with a current of up to 20mA and a voltage of 3.2V, enabling the device to be easily incorporated into various circuits and applications.

Working Principle

The LS A676-R1S1-1-Z works by providing a current flow across the LED when a positive voltage is applied to its anode and a negative voltage is applied to its cathode. The integrated circuit driver circuit controls the current flow and protects the LED from high voltage, reverse voltage and over-current conditions. The current flow produces light which can be used to indicate a wide range of system statuses. For example, it can be used as an indicator of system status such as on/off, working, or in error.

Conclusion

The LS A676-R1S1-1-Z is a discrete LED device designed for providing an indication of system status. It comprises of a LED assembly and a driver circuit in a standard 6-pin plastic package. The integrated circuit driver provides protection against high voltage, reverse voltage and over-current conditions, enabling the device to be used in various applications. The LS A676-R1S1-1-Z is suitable for use in automotive electronics, industrial, consumer goods and household appliances.
