TBD62503AFWG,EL

Overview

The TBD62503AFWG,EL is a low-side gate driver IC from Toshiba Semiconductor and Storage. It features seven independent DMOS transistor arrays configured as inverting drivers. The device supports a maximum load voltage of 50V and delivers an output current of 300mA per channel. It operates within a supply voltage range of 2.5V to 25V and functions reliably across a temperature range of -40°C to +85°C. Packaged in a surface-mount format, it integrates high-voltage outputs suitable for driving various loads directly.

Feature Summary

• Integrates seven independent low-side DMOS transistor arrays for multi-channel load control
• Provides inverting logic configuration for direct interface with standard digital signals
• Supports high-voltage output capability up to 50V for robust load driving
• Operates on a single power supply without requiring separate Vcc/Vdd biasing

Applications

• Driving relay coils in industrial control systems
• Actuating solenoids and hammer mechanisms
• Powering lamp arrays and LED display modules
• General-purpose low-side switching for peripheral devices

Procurement Notes

Verify the exact suffix 'AWG' against official Toshiba documentation to confirm package dimensions and tape specifications. Ensure compatibility with your PCB footprint for the specific SOP variant. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when multiple low-side switching channels are required in a compact form factor. It is suitable for applications needing 50V withstand voltage and 300mA continuous current per channel. Consider thermal management if operating near maximum current limits. Verify input logic levels match your microcontroller or driver circuitry.

Part Context

This part belongs to the TBD62503 series of DMOS transistor arrays. It serves as a modern replacement for older bipolar-based drivers like the TD62503FG, offering higher efficiency and lower drive current requirements. The series is designed for general-purpose power switching in consumer and industrial electronics.
