TBD62308AFG,EL

Overview

The Toshiba TBD62308AFG,EL is a low-side DMOS transistor array gate driver featuring four independent channels. It operates within a supply voltage range of 4.5 V to 5.5 V and supports load voltages up to 50 V. Each channel delivers an output current of 1.5 A with a typical on-resistance of 370 mΩ. The device utilizes an inverting logic configuration and consumes 200 µA of quiescent current. It is housed in a 16-pin HSOP surface-mount package and functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates four low-side N-channel DMOS outputs for driving high-current loads
• Features inverting input logic for direct interface with standard digital controllers
• Provides robust thermal performance with specified power dissipation capabilities

Applications

• Solenoid valve control systems
• DC motor drive circuits
• Relay switching applications
• General-purpose load drivers in industrial equipment

Procurement Notes

Verify the specific suffix EL indicates tape and reel packaging when ordering. Confirm the HSOP-16 package variant matches your PCB footprint requirements. Ensure the 4.5 V to 5.5 V supply voltage constraint aligns with your system design. Check RoHS compliance status if required by your manufacturing standards. Validate the inverting logic configuration against your control signal polarity.

Selection Notes

Select this component when four independent low-side switches are required with 1.5 A continuous current capability. The 370 mΩ on-resistance offers efficient power handling for moderate loads. The HSOP-16 package suits space-constrained surface-mount designs. Consider the inverting logic requirement before integration. This part is suitable for 5 V logic systems interfacing with higher voltage loads up to 50 V.

Part Context

This device belongs to the TBD62308 series of DMOS transistor arrays manufactured by Toshiba Semiconductor and Storage. It serves as a dedicated driver for inductive and resistive loads requiring multiple low-side switching channels. The series provides integrated protection features common to modern power management ICs. It complements other variants like the AFAG and APG models which differ primarily in package type.

Replacement Considerations

TBD62308AFAG,EL (SSOP-24 package) and TBD62308APG,HZ (DIP-16 package) offer functional equivalence with different physical footprints. Verify pin compatibility and thermal characteristics when substituting. Ensure the replacement maintains the 1.5 A output current rating and 50 V load voltage tolerance.
