TBD62384AFWG,EL

Overview

The Toshiba TBD62384AFWG,EL is an eight-channel low-side DMOS transistor array designed for interface driving applications. It operates with a supply voltage range of 4.5 V to 5.5 V and supports load voltages up to 50 V. Each channel provides a maximum output current of 400 mA or 500 mA depending on the specific datasheet reference, with a typical on-resistance of 1.5 ohms. The device features inverting logic inputs and is housed in a surface-mount 18-SOP (PSOP-18) package. It functions within a temperature range of -40°C to +85°C and includes internal protection against thermal shutdown.

Feature Summary

• Integrates eight independent N-channel DMOS outputs for high-current switching
• Features inverting input logic for direct microcontroller interfacing
• Includes built-in thermal shutdown circuitry for overtemperature protection
• Supports low-side configuration with wide load voltage tolerance

Applications

• Driving solenoids and relays in industrial control systems
• Actuator control in automotive electronic modules
• General-purpose power switching for peripheral devices
• Interface drivers for motor control circuits

Procurement Notes

Verify the exact suffix designation when ordering, as packaging variations such as EL and EHZ may exist. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure the selected package type matches the PCB footprint requirements. Check for any specific handling instructions related to moisture sensitivity levels during storage and assembly processes.

Selection Notes

Select this component for applications requiring multiple low-side switches with moderate current capabilities. The 18-SOP package is suitable for surface-mount assembly where space efficiency is prioritized. Consider the inverting logic requirement when designing the control interface. Evaluate thermal management needs based on the total power dissipation and ambient operating conditions to ensure reliable performance within the specified temperature range.

Part Context

This part belongs to the TBD62384 series of DMOS transistor arrays manufactured by Toshiba Semiconductor and Storage. It is categorized under Power Management ICs, specifically as a Driver IC or Load Switch. The series is designed for general-purpose interface driving tasks, offering a compact solution for controlling multiple loads from a single integrated circuit compared to discrete transistor solutions.

Replacement Considerations

The TBD62384APG is a pin-compatible alternative available in a PDIP-18 through-hole package. Both parts share similar electrical characteristics but differ in mounting style. Verify that the thermal performance and package dimensions are acceptable for the target application before substituting.
