12-Channel, 16-Bit ES-PWM RGB LED Driver with 3.3V Linear Regulator - TLC5971

TLC5971 (ACTIVE)

12-Channel, 16-Bit ES-PWM RGB LED Driver with 3.3V Linear Regulator

 

Description

The TLC5971 device is a 12-channel, constant-current sink driver. Each output channel has individually adjustable currents with 65536 PWM grayscale (GS) steps. Also, each color group can be controlled by 128 constant-current sink steps with the global brightness control (BC) function. GS control and BC are accessible through a two-wire signal interface. The maximum current value for each channel is set by a single external resistor. All constant-current outputs are turned off when the IC is in an overtemperature condition.
