Description

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. The TLC59281 is a 16-channel, constant-current sink LED driver.
