TLC69664YBHR TI LED Driver | 24-DSBGA (1.58X2.43) | 48-Channel, 16-Bit PWM

Product Overview

The TLC69664YBHR is a high-performance 48-channel constant-current LED driver from Texas Instruments, designed for precise current regulation and advanced dimming control. Housed in a compact 24-DSBGA (1.58x2.43 mm) package, it integrates 16-bit PWM dimming and 8-bit analog dimming for smooth, flicker-free brightness adjustment. With a maximum output current of 50 mA per channel, it supports flexible current setting via external resistors. The device features a 3-wire serial interface (SDI, SCLK, LATCH) for data communication, enabling daisy-chain operation for multiple drivers. It operates over a wide supply voltage range of 3.0V to 5.5V and includes thermal shutdown and LED open/short detection for robust system protection.
