TB9081FG

Overview

The TB9081FG is a three-phase brushless DC motor controller designed for automotive applications, certified to AEC-Q100 standards. It operates within a supply voltage range of 4.5 V to 28 V and supports a maximum operating temperature of +125 °C. The device features an integrated microcontroller with a 4 MHz working frequency and provides 11 output channels. It is housed in an LQFP-64 surface-mount package with a power dissipation rating of 515 mW.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 qualification standards
• Integrated system-on-chip architecture combining motor drive and control logic
• Supports low-voltage operation starting at 4.5 V for flexible power management

Applications

• Control of three-phase brushless DC motors in automotive systems
• Motion control modules requiring AEC-Q100 certified components
• Embedded motor driver circuits in vehicle electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and functional configuration. Confirm that the component meets the required AEC-Q100 reliability grade for your specific automotive application environment. Check humidity sensitivity levels and storage conditions prior to assembly to prevent moisture-induced damage during reflow soldering processes.

Selection Notes

Select this component when designing automotive motor control systems that require integrated MCU functionality alongside power driving capabilities. Ensure the design accommodates the LQFP-64 package dimensions and thermal requirements given the 515 mW power dissipation limit. Verify that the 4 MHz processing speed and 11 output channels meet the specific control logic and interface demands of the target motor application.

Part Context

This part belongs to Toshiba's SmartMCD series, which integrates motor drivers with Arm Cortex-M based microcontrollers. These system-level chips are engineered to provide compact, high-performance solutions for controlling both brushed and brushless DC motors in automotive environments while supporting communication interfaces like LIN.

Replacement Considerations

Consult Toshiba's official obsolescence notices or cross-reference guides for confirmed substitute part numbers. Do not assume functional compatibility with other three-phase controllers without verifying pinouts, voltage ratings, and automotive certification status.
