ZHCSM81A October 2020 – December 2020 TLC6C5748-Q1
PRODUCTION DATA
If the die temperature of TLC6C5748-Q1 reaches the thermal shutdown threshold TSD_R, the LED outputs of TLC6C5748-Q1 shut down to protect the device from damage. OUTB8's LOD & LSD bit will be set simultaneously to indicate this fault. The device restarts the LED outputs when temperature drops by TSD_HYS amount. OUTB8's LOD & LSD bit will also be reset when TSD fault is recovered.
The internal temperature sensing block is closest to OUTB8 channel. If some channels of TLC6C5748-Q1 need to be left unused, not leaving OUTB8 / OUTG8 / OUTR8 channel unused is recommended. This is to avoid the internal temperature sensing block in the coldest area of the die.
