The TLC5944RHBT is a 16-channel, constant current sink LED driver capable of delivering up to 60 mA per channel. It features 12-bit pulse-width modulation (PWM) control with 4096 grayscale steps and 6-bit dot correction for brightness adjustment across channels. The device includes an internal pre-charge FET to mitigate ghosting effects in multiplexed LED systems. It supports a supply voltage range of 3.0 V to 5.5 V and can operate with LED power supply voltages up to 15 V. The TLC5944RHBT also incorporates thermal shutdown protection, pre-thermal warning, and LED open detection, enhancing reliability in various applications. It is suitable for monochrome, multicolor, and full-color LED displays, operating within a temperature range of -40¬8C to +85¬8C. The device communicates via a serial interface with a data transfer rate of 30 MHz and a grayscale control clock frequency of 33 MHz.
