TLC59482 (ACTIVE)

16-Channel, 16-Bit PWM LED Driver with 6-Bit Global Brightness

 

Description

The TLC59482 is a 16-channel, constant-current sink driver. Each channel has an individually-adjustable, pulse width modulation (PWM) grayscale (GS) brightness control with 65,536 steps. All channels have a 64-step global brightness control (BC). BC adjusts brightness deviation with other LED drivers. GS and BC data are accessible via a serial interface port.
