ZHCSM81A October 2020 – December 2020 TLC6C5748-Q1
PRODUCTION DATA
The TLC6C5748-Q1 can individually adjust the output current of each channel (OUTx0 to OUTx15, where x is R, G, or B) by using DC. The DC function allows the brightness deviations of the LEDs connected to each output to be individually adjusted. Each output DC is programmed with a 7-bit word, so the value is adjusted with 128 steps within the range of 26.2% to 100% of IOLCMax. DC data are programmed into the TLC6C5748-Q1 with the serial interface. When the device is powered on, the DC data in the control latch contains random data. Therefore, DC data must be written to the DC data latch before turning the constant-current outputs on. Table 8-9 summarizes the DC data value versus the set current value.
