Hi Team,

Using TLC59284DBQ, ESD testing has issues,
Air discharge (8KV) or contact discharge (4KV) LED driver chips may occasionally experience reset phenomena, and the chip's external power supply cannot solve the problem. The schematic diagram and PCB are shown in the following figure. Please help analyze. Thank you.
