The TLC5921 from Texas Instruments is a versatile 16-channel constant current LED driver designed for various lighting applications. It features a robust drive capability of 80 mA per channel, allowing for precise control of LED brightness.
The device operates within a power supply voltage range of 4.5 V to 5.5 V and supports a data transfer rate of up to 20 MHz, enabling efficient serial communication for controlling individual LED channels. The constant current output range can be set from 1 mA to 80 mA using a single external resistor, providing flexibility in current setting.
Key features include LED Open Detection (LOD) to signal LED disconnection and Thermal Shutdown (TSD) circuitry to protect the device from overheating. The TLC5921 is available in a 32-pin HTSSOP DAP package, suitable for board mounting.
With its constant current accuracy of ±1% typical and ±4% maximum error between bits, the TLC5921 ensures consistent illumination. The input/output signal levels are CMOS compatible, facilitating integration into existing digital systems.
