TLC5921 Datasheet (Texas Instruments)

TLC5921, LED DRIVER

The TLC5921 is a current-sink constant current driver incorporating shift register and data latch.

The current value at constant current output can be set by one external register.

The device also incorporates thermal shutdown (TSD) circuitry which turns constant current output off when the junction
