LTD-5523AC application field and working principle

LED Character and Numeric display modules are used for a variety of applications. They are used for producing LED signs, LED clocks, LED scoreboards, LED thermometers, LED displays and more. Among these, LTD-5523AC from Lumex is one of the most popular LED Character and Numeric display modules.

The LTD-5523AC is a compact module with two-digit seven-segment displays. It has a built-in driver IC with the capability to control up to eight LEDs. The IC consists of an internal power supply, a trip buffer, current-limiting resistors, and transistors.

The LTD-5523AC can be connected to a host controller by using a digital interface like I2C or UART. The host controller can then issue commands to the module, instructing it to display a specific number or character. The LTD-5523AC includes a Brightness Adjustment Feature, allowing the user to adjust the lighting intensity depending on their environment and needs.

This module is mainly used in applications such as digital clocks, electronic signs, scoreboards, medical equipment, automotive displays and other industrial applications. It is a very cost-effective and durable solution, making it one of the most popular LED Character and Numeric display modules.

The LTD-5523AC works through an internal LED driver which is triggered by a periodic pulse. The pulse controls the intensity of the LED brightness, which is adjustable by controlling the current limiting resistors. The IC consists of two latch circuits, each one controlling four LEDs. It also includes a 10-bit counter and a 10-bit shift register for controlling the LEDs.

The LTD-5523AC has a peak current of up to 200mA, which turns on the LEDs for a certain time. The period of the LEDs is then determined by the user. The LTD-5523AC is also equipped with a software protection feature which is activated when the module is connected to a serial interface.

In addition to its robust performance, the LTD-5523AC offers high viscosity and low power consumption. This makes it very appealing to customers looking for cost-effective solutions in LED Character and Numeric display applications. The module is RoHS compliant and UL certified, adding to its reliability when used in different applications.

The LTD-5523AC is a valuable choice for those who need a robust, cost-effective solution in a two-digit seven-segment display module. It is a reliable, durable and low-maintenance solution with a great power efficiency and high visibility.
