TLC59211IPWR

Overview

The TLC59211IPWR is an LED driver IC featuring eight linear constant-current sink channels in a 20-TSSOP package. It operates on a supply voltage range of 3 V to 5.5 V with a maximum output current of 200 mA per channel. The device supports PWM dimming and includes thermal shutdown protection. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Eight-channel linear constant-current sink architecture for uniform LED control
• Integrated pulse-width modulation (PWM) interface for precise brightness adjustment
• Built-in thermal shutdown circuitry to prevent damage during overheating events

Applications

• Portable electronic display backlighting systems
• General-purpose indicator lighting circuits
• Low-power LED panel illumination

Procurement Notes

Verify the specific suffix IPWR confirms the TSSOP-20 surface-mount package variant. Confirm RoHS compliance status matches project requirements. Ensure the operating voltage range aligns with the system power supply specifications before finalizing procurement.

Selection Notes

Select this component when eight independent low-voltage LED channels are required. It is suitable for applications needing simple serial data input without complex external regulation. Consider alternative packages if through-hole mounting or higher channel counts are necessary.

Part Context

This part belongs to the Texas Instruments TLC5921x family of LED drivers. It shares functional similarities with other members like the TLC59211IN, differing primarily in packaging technology. The series provides standardized solutions for multi-channel LED control in consumer electronics.

Replacement Considerations

The TLC59211IN serves as a pin-compatible through-hole alternative within the same product family.
