Dear expert,
We have designed TLC5923 and face an output current drop issue now.
one of channel o/p current will drop around 90uA when turn off other channel output(total o/p current is around 200mA).
For example, CH#1 output 5mA; CH#2,3,4 total output current is 210mA. After shutdown CH#2,3,4, CH#1 will drop 90uA.
May I know why? And how to solve this issue?
Thanks!
-Ben
