TLC59283DBQR

16通道恒流LED驱动器，预充电FET 16-Channel, Constant-Current LED Driver with Pre-Charge FET

DESCRIPON

The TLC59283 is a 16-channel, constant-current sink light-emitting diode LED driver. Each channel can

be individually controlled with a simple serial communications protocol that is compatible with 3.3-V or 5-V CMOS logic levels, depending on the operating VCC.
