TLC59461PWPR

Overview

The TLC59461PWPR is a linear LED driver IC featuring 16 independent channels with 40mA output current per channel. It operates within a supply voltage range of 3V to 5.5V and supports an output voltage up to 17V. The device utilizes a serial shift register topology for data input and includes internal switches. It is housed in a 28-PowerTSSOP package with dimensions of 0.173 inches (4.40mm) width. The component functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates dot correction capabilities for individual pixel brightness adjustment
• Includes fault detection mechanisms for open and short circuit identification
• Supports grayscale PWM control for precise dimming applications

Applications

• LED backlighting systems
• Signage displays

Procurement Notes

Verify the specific suffix 'PWPR' indicates the tape-and-reel packaging format, distinct from tube variants like 'PW'. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 2) requirements for storage and handling during assembly processes.

Selection Notes

Select this component when 16-channel linear drive capability with integrated error flagging is required. Ensure the application voltage does not exceed the 17V output limit. Consider the PowerTSSOP thermal performance for high-density layouts requiring efficient heat dissipation.

Part Context

This part belongs to the Texas Instruments TLC5946 family of LED drivers. It shares functional similarities with the TLC5946 but may include specific enhancements or revisions. The PWPR suffix denotes the reel-packaged version intended for automated surface-mount assembly lines.

Replacement Considerations

The TLC5946PWPR is listed as an equivalent alternative. Verify pin compatibility and electrical specifications before substitution.
