TB6551FAG,C,8,EL

Overview

The TB6551FAG,C,8,EL is a Toshiba PWM brushless motor controller designed for three-phase full-wave drive applications. It operates within a supply voltage range of 6V to 10V and supports output currents up to 2mA with a working power supply current of 3mA. The device functions at frequencies between 2MHz and 8MHz, delivering an output voltage of 12V while maintaining a power dissipation of 1W. It is housed in a 24-SSOP surface-mount package and ensures reliable operation across a temperature range of -30°C to +115°C.

Feature Summary

• Integrates full-wave PWM control logic specifically engineered for three-phase brushless DC motors.
• Features a fully integrated design combining control circuitry and power stages within a single compact package.
• Supports high-frequency operation suitable for precise motor speed and position control requirements.

Applications

• Three-phase brushless DC motor control systems
• Precision motion control modules
• Automotive ignition driver circuits

Procurement Notes

Verify the specific suffix configuration (C,8,EL) against official Toshiba documentation to ensure compatibility with required packaging and environmental standards. Confirm that the SSOP-24 footprint matches the target PCB layout. Validate thermal management strategies given the 1W power dissipation rating and operating temperature limits before finalizing component selection.

Selection Notes

Select this component when designing systems requiring dedicated three-phase brushless motor control with low output current capabilities. Ensure the input voltage remains strictly within the 6V to 10V range to prevent operational failure. Consider the 24-SSOP package constraints for board space and verify that the operating frequency range aligns with the system's timing requirements.

Part Context

This part belongs to the TB6551 series of motor controllers manufactured by Toshiba Semiconductor and Storage. The series focuses on integrated solutions for brushless motor applications, distinguishing itself from brushed motor drivers like the TB6552 through its specific three-phase full-wave PWM architecture and associated control logic.

Replacement Considerations
