TB62785NG

Overview

The TB62785NG is an integrated circuit LED driver manufactured by Toshiba Semiconductor and Storage. It features eight linear output channels with a maximum current of 50mA per channel. The device operates within a supply voltage range of 4.5V to 5.5V and supports load voltages up to 17V. Designed for through-hole mounting, it utilizes a 24-SDIP package measuring 7.62mm in width. The component functions as a shift register-based driver suitable for dimming applications across a wide operating temperature range from -40°C to 85°C.

Feature Summary

• Integrates eight independent linear output channels for precise current control
• Utilizes internal shift register topology for serial data input and parallel output distribution
• Supports analog dimming functionality for adjustable brightness levels

Applications

• Seven-segment display panel driving
• Numeric indicator lighting systems
• General-purpose LED array illumination

Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant matches the required package type and lead configuration for your PCB layout. Cross-reference the manufacturer's latest datasheet to validate environmental compliance status and moisture sensitivity level prior to final procurement decisions.

Selection Notes

Select this component when a through-hole solution is required for low-current LED applications. The 24-SDIP package facilitates easy prototyping and manual assembly processes. Consider the linear regulation approach for simpler circuit designs where complex PWM generation is not necessary. Evaluate the 50mA output capability against the total current requirements of the connected display segments.
