ZHCSM81A October 2020 – December 2020 TLC6C5748-Q1
PRODUCTION DATA
Large surge currents may flow through the device and the board on which the device is mounted if all 48 outputs turn on simultaneously at the start of each GS cycle. These large current surges can introduce detrimental noise and electromagnetic interference (EMI) into other circuits. The TLC6C5748-Q1 independently turns the outputs on with a series delay for each group to provide a soft-start feature. The output current sinks are grouped into eight groups. The first output group that is turned on or off are OUTR4, OUTG4, OUTB4, OUTR11, OUTG11, and OUTB11; the second output group is OUTX0 and OUTX15; the third output group is OUTX5 and OUTX10; the fourth output group is OUTX1 and OUTX14; the fifth output group is OUTX2 and OUTX13; the sixth output group is OUTX6 and OUTX9; the seventh output group is OUTX3 and OUTX12; and the eighth output group is OUTX7 and OUTX8. Each output group is turned on and off sequentially with a small delay between groups.
