TC62D749CFNAG

Overview

The TC62D749CFNAG is a linear LED driver IC manufactured by Toshiba Semiconductor and Storage. It features 16 constant current output channels, each capable of delivering up to 90mA. The device operates on a supply voltage ranging from 3V to 5.5V, with individual output voltages reaching up to 17V. Packaged in a 24-SSOP format, it integrates internal switches and functions as a shift register for dimming control. The component is designed for surface-mount installation and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides 16 independent constant current output channels for precise LED control
• Integrates internal switching topology within a shift register architecture
• Supports linear dimming functionality for brightness adjustment

Applications

• LED lighting systems
• Display backlighting applications
• General illumination circuits

Procurement Notes

Verify the specific suffix 'CFNAG' against official Toshiba documentation to confirm package type and tape/reel specifications. Ensure compatibility with 24-SSOP footprint requirements. Confirm RoHS3 compliance status if environmental regulations apply to the target assembly. Cross-reference the part number with authorized distributors to avoid obsolete or non-conforming variants.

Selection Notes

Select this component when a high-channel-count LED driver with integrated shift register capability is required. The 90mA per channel limit suits standard indicator and general lighting LEDs rather than high-power emitters. Consider the linear topology efficiency constraints compared to switching drivers. Verify that the 3V to 5.5V input range aligns with the system power supply design.

Part Context

This part belongs to the TC62D749 series of LED drivers from Toshiba Semiconductor and Storage. It is distinct from similar models like the TC62D748 through specific pinout or functional variations defined in the datasheet. The CFNAG suffix denotes the specific packaging and handling configuration. It serves as a dedicated solution for managing multiple LED strings in compact electronic devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult Toshiba's official replacement guide or distributor cross-reference tools for verified alternatives. Do not assume functional equivalence with other 16-channel drivers without detailed parameter comparison.
