TBD62381AFNG,EL

Overview

The Toshiba TBD62381AFNG,EL is a low-side gate driver featuring an eight-channel DMOS transistor array. It operates within a supply voltage range of 4.5 V to 5.5 V and supports loads up to 50 V. Each channel delivers a maximum output current of 500 mA with a typical on-resistance of 2.5 Ohms. The device utilizes CMOS logic for inverting control signals and exhibits switching delays of up to 1 us. It functions reliably between -40°C and +85°C, dissipating up to 960 mW of power while consuming only 60 uA of quiescent current.

Feature Summary

• Integrates eight independent low-side DMOS outputs for driving multiple loads simultaneously
• Utilizes standard CMOS logic inputs for direct interfacing with microcontrollers
• Provides high-current sinking capability suitable for inductive and resistive loads

Applications

• Solenoid valve control systems
• Relay driver circuits
• LED matrix arrays
• Small motor control interfaces

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm tape-and-reel packaging specifications. Ensure the SSOP-18 package dimensions match your PCB footprint requirements. Cross-reference RoHS compliance status directly with the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when eight synchronized low-side channels are required within a compact surface-mount form factor. It is appropriate for designs needing moderate current handling without external heat sinks. Consider alternative packages if through-hole mounting or higher thermal dissipation capabilities are necessary for the specific application environment.

Part Context

This part belongs to Toshiba’s TBD623xx series of DMOS transistor arrays designed for general-purpose load driving. These devices are engineered to replace discrete transistor solutions, simplifying circuit design by integrating protection diodes and logic interfaces into a single monolithic structure.

Replacement Considerations

TBD62381APG offers identical electrical performance in a DIP-20 through-hole package. TBD62381AFWG,EL provides the same functionality in a PSOP-18 surface-mount package.
