The TLC5926/TLC5927 is designed for LED displays and LED lighting applications with open-load, shorted-load, and overtemperature detection, and constant-current control. The TLC5926/TLC5927 contains a 16-bit shift register and data latches, which convert serial input data into parallel output format. At the TLC5926/TLC5927 output stage, 16 regulated-current ports provide uniform and constant current for driving LEDs within a wide range of VF (Forward Voltage) variations. Used in systems designed for LED display applications (e.g., LED panels), TLC5926/TLC5927 provides great flexibility and device performance. Users can adjust the output current from 5 mA to 120 mA through an external resistor, Rext, which gives flexibility in controlling the light intensity of LEDs. TLC5926/TLC5927 is designed for up to 17 V at the output port. The high clock frequency, 30 MHz, also satisfies the system requirements of high-volume data transmission.

The TLC5926/TLC5927 provides a Special Mode in which two functions are included, Error Detection and Current Gain Control. In the TLC5926/TLC5927 there are two operation modes and three phases: Normal Mode phase, Mode Switching transition phase, and Special mode phase. The signal on the multiple-function pin OE(ED2) is monitored, and when an one-clock-wide short pulse appears on OE(ED2), TLC5926/TLC5927 enters the Mode Switching phase. At this time, the voltage level on LE(ED1) determines the next mode into which the TLC5926/TLC5927 switches.

In the Normal Mode phase, the serial data is transferred into TLC5926/TLC5927 via SDI, shifted in the shift register, and transferred out via SDO. LE(ED1) can latch the serial data in the shift register to the output latch.OE(ED2) enables the output drivers to sink current.

In the Special Mode phase, the low-voltage-level signal OE(ED2) can enable output channels and detect the status of the output current, to tell if the driving current level is enough or not. The detected error status is loaded into the 16-bit shift register and shifted out via SDO, along with the CLK signal. The system controller can read the error status to determine whether or not the LEDs are properly lit. In the Special Mode phase, TLC5926/TLC5927 also allows users to adjust the output current level by setting a runtime-programmable Configuration Code. The code is sent into TLC5926/TLC5927 via SDI. The positive pulse of LE(ED1) latches the code in the shift register into a built-in 8-bit configuration latch, instead of the output latch. The code affects the voltage at R-EXT and controls the output-current regulator. The output current can be adjusted finely by a gain ranging from 1/12 to 127/128 in 256 steps. Therefore, the current skew between ICs can be compensated within less than 1%, and this feature is suitable for white balancing in LED color-display panels

    Censtry is good company,Mr kim always keep his promised,.thanks.i hope we can cooperate with them again .

  • **KHILESH *** 2023-12-04

    John is very easy to work with, has target, knows what he wants, when, where, and how. He was able to take some excess off our hands in less than 30 minutes from the initial call. I would recommend working with John to anyone.
