16-Channel, 12-Bit PWM LED Driver With 6-Bit Dot Correction And Pre-Charge FET

The TLC5944 is a 16-channel, constant current sink driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 64 constant sink current (dot correction) steps. The dot correction (DC) adjusts for brightness variations between LEDs Both grayscale (GS) control and DC are accessible via a common serial Interface port. The maximum current value of all 16 channels CAN be set by a single external resistor. The TLC5944 has an internal pre-charge FET to prevent the ghost-lighting phenomenon that occurs on multiplexed LED systems. The TLC5944 has three error detection circuits for LED open detection (LOD), a thermal error flag (TEF), and a pre-thermal warning (PTW). The LOD detects a broken or disconnected LED and a shorted LED to GND during the Display period. The TEF indicates a too-high temperature condition; when the TEF is set, all output drivers are turned off by the thermal shutdown (TSD) protection. Additionally, when the TEF is cleared, all output drivers are restarted. The PTW indicates that the IC is operating in a high temperature condition. The output drivers remain on when PTW is set.
