Description

The TLC5942 is a 16-channel, constant current sink driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 128 constant current sink steps for dot correction. Dot correction adjusts the brightness variations between LEDs. Both grayscale control and dot correction are accessible via separate, dedicated serial interface ports. The maximum current value of all 16 channels can be set by a single external resistor.

The TLC5942 has two error detection circuits for LED open detection (LOD) and a thermal error flag (TEF). LOD detects a broken or disconnected LED during the display period. TEF indicates an over-temperature condition; when a TEF is set, all output drivers are turned off.
