TB62D612FTG,EL

Overview

The TB62D612FTG,EL is a 24-channel constant-current LED driver IC manufactured by Toshiba Semiconductor and Storage. It features linear output control with analog, I2C, and PWM dimming capabilities. The device supports an output current of 40mA per channel and operates within a supply voltage range of 3V to 5.5V. Output voltage is limited to 4V. It utilizes a 36-WQFN (6x6) package with exposed pad for surface mount installation. The component functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates 24 independent constant-current channels for high-density LED arrays
• Supports multiple dimming methods including analog, I2C digital, and PWM signals
• Incorporates internal switches to simplify external circuit design

Applications

• High-resolution LED display panels
• Backlighting systems for mobile devices
• Automotive interior lighting modules

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm packaging and tape specifications. Ensure compatibility with I2C bus speeds and logic levels in the target system. Confirm thermal management requirements for the 36-WQFN package under maximum load conditions. Cross-reference pin assignments with the latest datasheet revision to avoid integration errors.

Selection Notes

Select this component when a high channel count is required within a compact footprint. The integrated I2C interface reduces microcontroller GPIO usage compared to parallel control schemes. Consider the linear regulation type for applications where noise sensitivity is lower than in switching regulator designs. Evaluate the 40mA output limit against total LED string current requirements.

Part Context

This part belongs to the TB62D series of LED drivers from Toshiba. It shares functional similarities with other models in the family but differs in output count and package configuration. The TB62D612 specifically targets applications requiring 24 channels, distinguishing it from higher or lower channel variants like the TB62D787 or TB62D786.

Replacement Considerations

TB62D612FTG is a compatible variant without the EL suffix, potentially differing only in packaging format.
