TLC5947RHBT

Драйвер светодиода, 24 выхода, постоянный ток, 3В-5.5В (Vin), 30МГц, 30В/30мА, VQFN-32.

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.
