Драйверы светодиодных дисплеев TLC5971PWPR

Драйвер светодиода , 12 выходов, постоянный ток, 6В-17В (Vin), 12МГц, 17В/60мА, HTSSOP-20

The TLC5971PWPR is a 12-channel, Constant-current Sink Driver, each output channel has individually adjustable currents with 65536 PWM greyscale (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 via 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.
