TBD62781APG

Overview

The Toshiba TBD62781APG is an eight-channel high-side DMOS transistor array gate driver designed for switching loads up to 50V. It features a non-inverting logic configuration with a maximum output current of 500mA per channel. The device operates within a supply voltage range of 2V to 50V and supports through-hole mounting in a 20-pin DIP package. It functions reliably across an extended temperature range from -40°C to +85°C, providing robust performance for general-purpose load driving applications requiring high-side control.

Feature Summary

• Integrates eight independent high-side DMOS switches for simultaneous multi-channel load control
• Supports direct interface with standard logic inputs via non-inverting configuration
• Capable of driving heavy loads with up to 500mA continuous output current per channel
• Operates over a wide power supply voltage range suitable for various system architectures

Applications

• Industrial motor control systems requiring high-side switching
• Solenoid and relay driver circuits in automation equipment
• General-purpose load switching in consumer electronics
• Lighting control arrays for high-voltage LED or lamp drivers

Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected package variant matches the intended PCB layout requirements. Cross-reference the operating temperature range with application constraints to guarantee reliability under extreme conditions. Confirm RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when high-side switching capability is required for loads exceeding standard low-side driver limits. Consider the 500mA output capacity for moderate power applications without external heat sinking. Evaluate the non-inverting logic requirement against existing microcontroller outputs to avoid additional inversion circuitry. Assess the DIP package suitability for prototyping or through-hole manufacturing processes compared to surface-mount alternatives.

Part Context

This part belongs to Toshiba's TBD6278x series of DMOS transistor arrays, which are optimized for high-current switching tasks. The series provides integrated protection features and robust construction for industrial environments. Compared to discrete solutions, this IC offers reduced board space and simplified design complexity by combining multiple drivers into a single package.
