DESCRIPTION/ORDERING INFORMATION  
The TLC5916/TLC5917 is designed for LED displays and LED lighting applications with constant-current control  
and open-load, shorted-load, and overtemperature detection. The TLC5916/TLC5917 contains an 8-bit shift  
register and data latches, which convert serial input data into parallel output format. At the output stage, eight  
regulated current ports are designed to provide uniform and constant current for driving LEDs within a wide range  
of VF variations. Used in system design for LED display applications, e.g., LED panels, it 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. The devices are 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 TLC5916/TLC5917 provides a Special Mode in which two functions are included, Error Detection and  
Current Gain Control. 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 to  
determine the mode. When an one-clock-wide pulse appears on OE(ED2), the device enters the Mode Switching  
phase. At this time, the voltage level on LE(ED1) determines the mode to which the TLC5916/TLC5917 switches.  
In the Normal Mode phase, the serial data can be transferred into TLC5916/TLC5917 via the pin SDI, shifted in  
the shift register, and transferred out via the pin 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 determine if the driving current level is sufficient. The detected Error Status is  
loaded into the 8-bit shift register and shifted out via the pin SDO, synchronous to the CLK signal. The system  
controller can read the error status and determine whether or not the LEDs are properly lit.  
In the Special Mode phase, the TLC5916/TLC5917 allows users to adjust the output current level by setting a  
runtime-programmable Configuration Code. The code is sent into the TLC5916/TLC5917 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 the terminal R-EXT and controls the output-current regulator. The output  
current can be finely adjusted 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%. This feature is suitable for white balancing in LED color  
display panels.
