MR3350 LED Indication - Discrete

The MR3350 is a very helpful and efficient tool in the Light Emitting Diode (LED) indication-discrete field of application. It is used to accurately monitor and control the intensity of light that is used to signal the status or activity of a system or device. This discrete LED indication is especially used for when one wants to represent specific values in a system, to easily observe the activation or deactivation of output or functions, or for indication of alerts in a control system.

When used as a discrete LED indication, the MR3350 functions by using a low-voltage current source to feed the LED’s through an appropriate resistor. It will sense the forward voltage drop across the LED itself. By measuring this voltage, the MR3350 is then able to accurately measure the LED current. This current can signal whether something is active or inactive in a system.

The MR3350 is key in discrete LED indication due to its ability to precisely regulate the current fed to the LED’s. It is able to set the upper and lower thresholds for the LED’s that allows for optimal illumination of the LED’s. The precision of the MR3350’s current regulation is also able to extend the life of an LED. For example, at a forward voltage of 2.2V, the MR3350’s accurate regulation will prevent the LED from being over-driven, increasing its lifespan.

The MR3350’s discrete LED indication offers a maximum of four independent LED’s, with a maximum forward current of 30mA each. This allows the user to make an effective indication of multiple values or activities in a system easily. The maximum PWM frequency is also adjustable, allowing for a more descriptive LED indication. The MR3350 is also compatible with any LED that is matched to its range of forward voltage.

Due to its precision, the MR3350 is perfect for representing values or activities in a system. Its ability to accurately measure the forward voltage drop allows it to adjust the LED’s current precisely, making it a reliable and efficient tool in the LED indication-discrete field of application.
