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.
