TLC5948APWP

Overview

The TLC5948APWP is a 16-channel LED driver from Texas Instruments, housed in an HTSSOP-28 package. It operates on a supply voltage of 3 V to 5.5 V with a maximum power current of 60 mA. The device supports SMD/SMT installation and functions within a temperature range of -40°C to +85°C. Key features include dot correction, error flags, fault detection, and LED open/short detection. Output currents are specified at -1 mA for high level and 1 mA for low level.

Feature Summary

• Integrates full self-diagnosis capabilities including LED open and short circuit detection.
• Supports precise brightness control through dot correction and error flagging mechanisms.
• Utilizes ES-PWM technology for efficient LED illumination management.

Applications

• LED lamp applications requiring global brightness control
• General-purpose LED display systems
• High-brightness lighting fixtures

Procurement Notes

Verify the specific suffix 'PWP' corresponds to the tube packaging variant rather than the reel-based PWPR version. Confirm that the component meets RoHS standards as indicated in official specifications. Ensure compatibility with the required operating voltage range of 3 V to 5.5 V before integration into the final design.

Selection Notes

Select this model when full self-diagnosis and dot correction are required for 16-channel LED arrays. It is suitable for designs needing robust fault detection alongside standard PWM control. Consider the HTSSOP-28 package constraints for PCB layout and thermal management requirements.

Part Context

This component belongs to the TLC5948 series, designed specifically for LED lighting drivers. It distinguishes itself by offering comprehensive error detection alongside standard driving functions. The part is categorized under Driver ICs and serves as a specialized solution for complex LED matrix applications.

Replacement Considerations

The TLC5948PWPR is a direct functional substitute differing only in packaging format (reel vs. tube). Other family members like the TLC5945 may offer similar channel counts but lack specific ES-PWM features.

FAQ

What type of PWM control does the TLC5948APWP support?

It utilizes ES-PWM (Enhanced Serial Pulse Width Modulation) technology for controlling LED brightness across all 16 channels.

Does the device provide feedback on LED faults?

Yes, it includes full self-diagnosis features such as error flags and detection for both LED open and short circuits.
