产品概述

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 temperature exceeds the limit, and LED open detection (LOD) circuitry to report the LED was disconnected.
