TB62777FG,EL

Overview

The TB62777FG,EL is an 8-channel constant-current LED driver IC manufactured by Toshiba Semiconductor and Storage. It features a linear shift register interface for dimming control and supports up to 40mA per output channel. The device is housed in a 16-SSOP package and is designed for applications requiring precise current regulation across multiple LEDs.

Feature Summary

• Integrates an 8-channel constant-current sink with linear shift register functionality for simplified serial data input and dimming control.

Applications

• Display backlighting systems
• Indicator lighting circuits
• LED panel driver modules

Procurement Notes

Verify the specific suffix 'EL' against the official Toshiba datasheet to confirm packaging details and RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel specifications. Cross-reference the part number with authorized distributors to confirm availability and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when an 8-channel solution with integrated shift register capability is required. It is suitable for designs needing linear dimming control without external logic components. Consider the 16-SSOP package size for space-constrained PCB layouts.

Part Context

This part belongs to Toshiba's dedicated LED driver family, specifically engineered for display and indicator applications. It combines power output stages with digital control interfaces to reduce system complexity. The TB62777 series is distinct from general-purpose logic drivers due to its optimized constant-current characteristics.

Replacement Considerations

Consult the official Toshiba replacement guide for direct equivalents. Verify pin compatibility and electrical parameters before substituting with other 8-channel LED drivers from different manufacturers.
