TB6640FTG,EL

Overview

The TB6640FTG,EL is a full-bridge DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS output transistors to provide robust motor control capabilities. The device supports a maximum power supply voltage of 40 V and delivers a continuous output current of 3 A. It features direct PWM control for efficient operation. Integrated protection mechanisms include under-voltage lockout (UVLO), short-circuit detection (ISD), and thermal shutdown (TSD). The component is housed in a WQFN48 package suitable for surface mount applications.

Feature Summary

• Integrates full-bridge power stage with DMOS technology for low on-resistance
• Provides comprehensive protection against under-voltage, short circuits, and over-temperature conditions
• Supports direct pulse-width modulation input for simplified interface design

Applications

• Brushed DC motor control systems
• Industrial automation equipment
• Home appliance motor drives

Procurement Notes

Verify the specific suffix EL indicates the tape and reel packaging configuration when ordering. Confirm the WQFN48 footprint matches the target PCB layout. Ensure the design accommodates the 40 V maximum voltage rating and 3 A current capability. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component for applications requiring a single-chip solution for brushed DC motors. It is suitable where space constraints favor the compact WQFN48 package. Consider the integrated protection features for enhanced system reliability. Compare against higher current variants if load requirements exceed 3 A.

Part Context

This part belongs to Toshiba's series of brushed DC motor driver ICs. It is designed to replace discrete MOSFET solutions by integrating control logic and power stages. The TB6640FTG offers a balance of performance and protection for mid-power motor applications.

Replacement Considerations

Check for pin-compatible alternatives within the same Toshiba family. Verify that substitute parts meet the 40 V and 3 A electrical limits. Ensure thermal management requirements are comparable due to similar power dissipation characteristics.
