TB9054FTG(EL)

Overview

The TB9054FTG(EL) is a Toshiba automotive-grade H-bridge motor driver designed for brushed DC motors. It integrates two channels with a 5A output capability and features an SPI interface for control. The device operates within a supply voltage range of 4.5V to 5.5V, drawing a typical quiescent current of 5.4mA. It supports PWM types and provides four outputs. The component is housed in a VQFN-40 package suitable for surface mount installation. It functions at a working frequency of 16MHz with a power dissipation of 5.18W. The unit is qualified under AEC-Q100 standards and endures temperatures from -40°C to +125°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 and Q006 standards
• Integrated dual-channel H-bridge architecture for precise motor control
• SPI communication interface for efficient digital command processing
• Wettable flank QFN40 packaging facilitating reliable inspection

Applications

• Automotive brushed DC motor actuation systems
• Vehicle seat adjustment mechanisms
• Power window and sunroof drive units
• HVAC blower fan control applications

Procurement Notes

Verify the specific ordering suffix matches the required wettable flank variant. Confirm that the VQFN-40 package aligns with the target PCB footprint. Ensure the design accommodates the specified 5.18W power dissipation through adequate thermal management. Validate that the system logic levels are compatible with the SPI interface requirements before finalizing the procurement order.

Selection Notes

Select this component when designing for automotive environments requiring robust motor driving capabilities. The integrated H-bridge structure simplifies circuit design compared to discrete solutions. Consider the thermal performance characteristics given the power dissipation limits. The SPI interface offers advantages in noise immunity and pin count reduction for complex control schemes.

Part Context

This part belongs to Toshiba's automotive motor driver portfolio, specifically engineered for high-reliability vehicle applications. It complements other series like the TB9053 by offering dual-channel functionality. The product line emphasizes compliance with strict automotive quality standards while providing efficient power management for various actuator types found in modern vehicles.

Replacement Considerations

Direct substitutes include the TB9053FTG(EL) for single or dual channel variations. Cross-reference the TB9051FTG(EL) if only a single channel is required. Verify pin compatibility and thermal specifications before substituting any alternative models from the manufacturer.
