德州仪器的不具有 LED 开路检测的 16 通道恒流 LED 驱动器
16-Channel, Constant-Current LED Driver

说明

The TLC59281 is a 16-channel, constant-current sink LED driver. Each channel can be turned on/off by writing serial data to an internal register. The constant-current value of all 16 channels is set by a single external resistor.
