TC62D748CFNAG(CBHJ

Overview

The TC62D748CFNAG is a 16-output constant current LED driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes a linear shift register topology for dimming control. The device operates within a supply voltage range of 3V to 5.5V, supporting output voltages up to 17V. Each channel provides a maximum output current of 90mA. The component is housed in a 24-SSOP package with dimensions of 6.00mm width. It functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates 16 independent constant current outputs for uniform LED illumination
• Employs linear shift register architecture for simplified serial data input and dimming control
• Features internal switching capability to manage high-side LED load connections

Applications

• LED backlighting systems for liquid crystal displays
• General-purpose LED lighting modules
• Display panel driving circuits requiring precise current regulation

Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements and thermal management constraints before procurement. Confirm RoHS compliance status through the manufacturer's latest product announcements.

Selection Notes

Select this component when designing systems requiring multiple synchronized LED channels with linear dimming capabilities. Consider the 24-SSOP footprint for surface-mount assembly processes. Evaluate the 90mA per-channel limit against total LED string current demands to ensure adequate drive capacity without exceeding thermal limits.

Part Context

This part belongs to the TC62D series of LED drivers from Toshiba Semiconductor and Storage. It shares functional similarities with models like the TC62D749CFG, differing primarily in packaging variations such as SSOP versus HTSSOP configurations. The series targets applications needing reliable, low-component-count solutions for multi-channel LED control.

Replacement Considerations

Direct substitutes include the TC62D749CFG for equivalent electrical performance in alternative packages. Verify pinout compatibility and thermal characteristics when cross-referencing with other Toshiba LED driver variants.
