Overview
The TB9053FTG(EL) is a Toshiba automotive-grade brushed DC motor driver featuring two H-bridge channels. It supports a VBAT supply range of 4.5V to 28V and a VCC range of 4.5V to 5.5V. The device delivers up to 5A per channel or 10A in parallel single-channel mode. It utilizes a 40-pin Power QFN package (6.0mm x 6.0mm). Key specifications include an operating temperature range of -40°C to +125°C, AEC-Q100 qualification, and SPI interface control.
Feature Summary
- Integrated dual-channel H-bridge architecture with low on-resistance DMOS FETs for efficient power delivery.
- SPI communication capability enabling motor control via daisy-chain connections to reduce microcontroller port usage.
- Comprehensive diagnostic functions including overcurrent protection, overtemperature shutdown, undervoltage detection, and open-load monitoring.
Applications
- Electronic throttle systems
- Engine valve actuators
- Power-folding side mirrors
- Electric door latches
Procurement Notes
Verify the specific suffix EL against official Toshiba documentation to confirm packaging details. Ensure the design accommodates the 40-pin Power QFN footprint dimensions. Confirm AEC-Q100 compliance requirements match the target automotive application standards before finalizing procurement.
Selection Notes
Select this component when system miniaturization is critical due to its compact 6.0mm square package. Choose this model if SPI-based control is required to minimize MCU pin count. Consider the 10A parallel drive capability for applications demanding higher current throughput from a single channel configuration.
Part Context
This part belongs to Toshiba's automotive motor driver family designed for electronic throttle and valve applications. It complements the TB9054FTG by offering similar electrical performance but utilizes a standard Power QFN package instead of the wettable flanks VQFN variant found in the TB9054 series.
Replacement Considerations
TB9054FTG(EL) offers identical electrical specifications but uses a Wettable Flanks VQFN-40 package instead of the Power QFN-40. Verify package compatibility and soldering process requirements before substitution.
