Product Description

The TLC5947RHBT is a 24-channel 12-bit PWM constant-current LED Sink Driver with 4MHz internal oscillator. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps. PWM control is repeated automatically with the programmed grayscale (GS) data. GS data are written via a serial interface port. The current value of all 24 channels is set by a single external resistor. It has a thermal shutdown (TSD) function that turn-OFF all output drivers during an over-temperature condition. All of the output drivers automatically restart when the temperature returns to normal conditions.
CMOS logic level I/O
Shift out data changes with falling edge to avoid data shift error
Auto display repeat function
Thermal shutdown (TSD) - Automatic shutdown at over-temperature conditions
Noise reduction - 4-channel Grouped delay to prevent inrush current
Constant-current accuracy - ±2% (typical) channel-to-channel and ±2% (typical) device-to-device
Green product and no Sb/Br
