HPA00479PWPR

Overview

The HPA00479PWPR is an LED display driver manufactured by Texas Instruments, belonging to the TLC5946 series. It features a 28-pin HTSSOP package and operates within a supply voltage range of 3 V to 5.5 V. The device provides sixteen channels with 12-bit PWM resolution for precise brightness control. Key electrical specifications include a maximum power dissipation of 3.958 W, a maximum supply current of 45 mA, and output currents ranging from -1 mA (high) to 5 mA (low). It supports surface mount installation and functions reliably between -40°C and +85°C.

Feature Summary

Integrates dot correction capabilities for uniform LED brightness across the display array.
Includes error flag functionality to report internal faults or communication errors.
Supports LED open and short detection for enhanced system reliability and diagnostics.

Applications

LED matrix displays
Signage systems
Digital signage

Procurement Notes

Verify the component designation against official manufacturer documentation to confirm that the HPA00479PWPR alias corresponds to the TLC5946 family specifications. Ensure compatibility with required operating temperatures and voltage ranges before integration. Cross-reference datasheet parameters for pinout and thermal characteristics to validate design suitability.

Selection Notes

Select this component when designing systems requiring high-resolution LED control with diagnostic feedback. The integrated dot correction simplifies calibration processes, while fault detection aids in maintaining display integrity. Consider the HTSSOP-28 package constraints and thermal management requirements associated with the specified power dissipation limits during PCB layout.

Part Context

This part is identified as an alias for the TLC5946 series within the Texas Instruments portfolio. It serves as a specialized driver for managing multiple LED outputs with individual pulse-width modulation control. The designation links directly to the broader TLC5946 product line known for its advanced display driving features.
