Discrete LED indication is a type of indicator microchip designed to offer a faint light or flashes of light to a larger area. The LNJ024X4ARA is a particularly notable microchip that used a pulse width modulation (PWM) circuit to indicate a warning, status, or presence. As one of the most versatile discrete LED microchips on the market, the LNJ024X4ARA has applications in many areas of industry.

Design and Structure

The LNJ024X4ARA is a two lead SMD flip chip. It includes a PWM modulation circuit with multiple output resistors and capacitors, enabling standard and burst control with adjustable pulse widths. The two leads on the microchip are reversed in the mounting position, allowing the device to be soldered on top of the circuit board with pins oriented towards the top.

The LNJ024X4ARA has an integrated red LED, reverse current protection, and low power consumption. It is designed to be configured as either a continuous or burst type LED indicator. The output configuration is determined by the resistor connected to the PWM control pin. For burst type LED configuration, the LED turns off for a preset time before coming on for a preset time.

Features and Benefits

The LNJ024X4ARA is designed to provide a highly efficient and reliable discrete LED indicator solution. It has several key features that make it suitable for a range of diverse applications, including low power consumption, reverse current protection, and adjustable pulse width. Other features include:

• Integrated red LED
• Standard and burst type output configuration
• Small form factor – 8-lead SMD
• Cost effective solution
• Low quiescent current and high efficiency

Typical Applications

The LNJ024X4ARA is a versatile discrete LED microchip that can be used in various applications, including:

• Automotive – LED indicators for vehicle speed, oil pressure, battery charge, and temperature.
• Security systems – LED indicators for alarms that indicate presence or status of triggers or actions.
• Consumer electronics – LED indicators for LCD displays, clocks, and telecommunication equipment.
• Industrial – LED indicators for control systems, touch screen displays, and process monitoring and control.
• LED cabinet lighting – LED indicators for cabinet lighting and other specialty lighting applications.

Working Principle

The LNJ024X4ARA is a discrete LED indicator with an integrated PWM circuit. It is designed to produce an instantaneous output voltage in response to changing input signals. As the input signal rises and falls, the PWM control adjusts the duty cycle of the output signal, allowing the LED to be turned on and off in bursts.

The LNJ024X4ARA is a versatile and reliable discrete LED indicator that can be used in a wide range of applications. It has a small form factor, low power consumption, and adjustable pulse widths, making it a cost-effective solution for any application requiring a discrete LED indicator.
