Description:

The TLC5941-Q1 device is a 16-channel, constant-current sink, LED driver. Each channel has anindividually adjustable 4096-step grayscale PWMbrightness control and a 64-step constant-current sink(dot correction), which both are accessible via a serialinterface. This device features two fault diagnosticcircuits. The LED open detection(LOD)indicates abroken or disconnected LED at an output terminal.The thermal error flag(TEF)indicates an overtemperature condition.The TLC5941-Q1 features two errorinformationcircuits. The LED open detection(LOD)indicates abroken or disconnected LED at an output terminal.The thermal error flag(TEF)indicates an overtemperature condition.
