TLC5943RHBR

Overview

The TLC5943RHBR is a Texas Instruments LED driver IC featuring 16 linear output channels. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum clock frequency of 30 MHz. Each channel provides an output current capability of 50 mA, with a maximum output voltage of 17 V. The device utilizes a 32-VQFN package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

Integrates 16 independent linear output channels for precise LED current control
Supports serial data input via standard SPI-compatible interface
Includes internal error flag output for fault detection monitoring

Applications

LED backlighting systems
General LED lighting applications

Procurement Notes

Verify the specific suffix 'RHBR' corresponds to the required tape-and-reel packaging configuration. Confirm that the 32-VQFN footprint matches the target PCB design. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the manufacturer part number against official datasheets to validate electrical specifications before procurement.

Selection Notes

Select this component when 16 individually controllable linear outputs are required. It is suitable for designs needing 50 mA per channel without external current-setting resistors. Consider the 32-VQFN package size constraints. Evaluate thermal dissipation capabilities within the specified ambient temperature range. Compare against PWM-based drivers if dimming resolution requirements differ significantly.

Part Context

This part belongs to the TLC5943 series of LED drivers from Texas Instruments. It is designed for applications requiring multiple constant-current sinks. The RHBR suffix indicates a specific reel-based packaging option. It shares functional similarities with other members of the family but differs in channel count and specific electrical characteristics compared to variants like the TLC5946 or TLC5947.
