LED control drive circuit diagram

The ET6201 is a LED display control drive circuit with a duty cycle of 1/7 to 1/8. It features 11 segment output gates and 1 segment/gate output, along with a display memory, control circuit, and key scanning circuit, which collectively form a highly reliable peripheral LED driving circuit. The device accepts serial data through a 4-wire serial interface and is packaged in an SOP32 form factor.

The ET6201 is designed to efficiently manage LED displays by controlling the illumination of individual segments based on the input data received through its serial interface. The duty cycle of 1/7 to 1/8 indicates that the circuit can operate with a high degree of efficiency, allowing it to drive multiple segments without excessive power consumption. This is particularly beneficial in applications where battery life is critical, such as in portable devices.

The architecture of the ET6201 includes 11 segment output gates that can be independently controlled to display various characters or symbols. The additional segment/gate output allows for further customization and flexibility in display configurations. The integrated display memory stores the data that dictates which segments should be illuminated, ensuring that the display can update quickly and accurately in response to user inputs or changes in the data stream.

The control circuit within the ET6201 manages the timing and sequencing of the display updates, while the key scanning circuit enables user interaction through buttons or switches. This functionality is crucial for applications where user input is required, such as in digital clocks, counters, or other informational displays.

The 4-wire serial interface simplifies the connection to microcontrollers or other digital systems, allowing for easy integration into existing designs. This interface typically consists of a clock line, a data line, a chip select line, and a ground connection, facilitating straightforward communication between the ET6201 and the controlling device.

The SOP32 packaging ensures that the ET6201 can be easily mounted on printed circuit boards (PCBs), making it suitable for a wide range of electronic applications. The compact size of the SOP32 package also contributes to the overall reduction in space required for assembly, which is an important consideration in modern electronic design.

In summary, the ET6201 is a versatile and efficient solution for driving LED displays, offering robust features that enhance display performance while maintaining low power consumption.
