TB6569FTG,8,EL

Overview

The TB6569FTG,8,EL is a full-bridge brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes Bi-CMOS technology to integrate control logic and power stages within a single package. The device supports a supply voltage range of 10V to 45V and delivers an output current of up to 4A. It accepts parallel and PWM interface signals for direct control. The component operates reliably across a temperature range of -40°C to +85°C and is housed in a compact 32-VQFN (5x5mm) surface-mount package with an exposed pad for thermal management.

Feature Summary

• Integrates full-bridge power stage with low on-resistance MOS transistors for high thermal efficiency
• Supports direct PWM input and constant current control via external components
• Includes comprehensive protection circuits such as overcurrent shutdown, overvoltage shutdown, and thermal shutdown
• Enables four operational modes including clockwise, counter-clockwise, short brake, and stop

Applications

• Brushed DC motor control in industrial automation equipment
• Motion control systems requiring integrated drive and logic
• General-purpose motor driver applications in consumer electronics

Procurement Notes

Verify the specific suffix EL indicates the tape and reel packaging configuration when ordering. Confirm that the 32-VQFN footprint matches the target PCB design, particularly regarding the exposed thermal pad requirements. Ensure compatibility with the 10V to 45V supply voltage range intended for the application. Check for RoHS3 compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component for designs requiring a fully integrated solution that combines logic control with high-current power switching. The Bi-CMOS process offers a balance of speed and power handling suitable for brushed DC motors. Consider the 32-pin QFN package for space-constrained layouts while ensuring adequate thermal dissipation strategies are implemented due to the exposed pad design.

Part Context

This part belongs to the TB6569 series of full-bridge DC motor drivers from Toshiba. It is designed to replace discrete solutions by integrating pre-drivers, logic, and power MOSFETs. The FTG variant specifically denotes the QFN package option, distinguishing it from other package types like BSOP or SSOP available within the same functional family.

Replacement Considerations

TB6642FTG,8,EL is listed as a substitute part number by the manufacturer.
