TLC5971RGET

The TLC5971RGET is a 12-channel 16-bit ES-PWM RGB constant-current LED Sink Driver with 3.3V linear regulator. Each output channel has individually adjustable currents with 65536 PWM grayscale (GS) steps. Also, each colour 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 over-temperature condition.

• Auto display repeat function
• Display timing reset function
• Internal and external selectable GS clock
• Thermal shutdown (TSD) with auto restart
• Unlimited device cascading
• Global brightness control (BC) - 7-bit (128 Steps) for each colour group
• Constant-current accuracy - ±1% (typical) channel-to-channel and ±1% (typical) device-to-device
• Green product and no Sb/Br
