TC62D748CFNAG,C,EB

Overview

The TC62D748CFNAG,C,EB 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 supports an operating supply voltage range from 3V to 5.5V. Each output channel provides a maximum current of 90mA, with a maximum output voltage of 17V. It features internal switches and is housed in a 24-HTSSOP package with a bare pad. The component operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates 16 constant current outputs for direct LED driving
• Utilizes linear shift register architecture for sequential data input and dimming control
• Includes internal switching elements to manage output channels

Applications

• LED display systems requiring constant current drive
• Portable electronic devices utilizing LED indicators or backlighting
• General lighting applications compatible with shift register control interfaces

Procurement Notes

Verify the specific suffix (CFNAG,C,EB) against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the ordering part number matches the exact tape-and-reel or cut-tape specifications required for your assembly process. Confirm RoHS compliance status directly with the supplier documentation prior to procurement.

Selection Notes

Select this component when a 16-channel constant current solution with linear dimming capability is required. The 90mA per channel rating suits standard indicator LEDs or low-power backlight arrays. Consider the 24-HTSSOP package constraints for PCB layout. Verify that the system logic levels are compatible with the shift register interface before integration.

Part Context

This part belongs to the TC62D7xx series of LED drivers from Toshiba Semiconductor and Storage. These integrated circuits are designed to simplify LED control by combining shift register functionality with power output stages. The series typically offers various output counts and current ratings to accommodate different display density requirements.

Replacement Considerations

Consult official Toshiba substitution lists for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering competitors, as shift register timing and current regulation methods may differ significantly between manufacturers.
