TB67H452FTG,EL

Overview

The TB67H452FTG,EL is a brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a half-bridge output configuration with four independent channels. The device supports a maximum supply voltage of 38 V and a minimum operating voltage of 6.3 V. Each channel delivers an output current of 3.5 A. The component operates within a temperature range of -20°C to +85°C and has a power dissipation rating of 1.3 W. It utilizes a QFN-48 package for surface mount installation.

Feature Summary

• Integrated half-bridge architecture providing four independent output channels for multi-motor control applications
• Capable of driving brushed DC motors with a continuous output current capacity of 3.5 A per channel
• Operates with a low quiescent supply current to minimize standby power consumption

Applications

• Brushed DC motor control in industrial automation equipment
• Motion control systems requiring multiple independent motor drives
• Automotive interior accessory drivers

Procurement Notes

Verify the specific suffix EL against the manufacturer's official datasheet to confirm packaging and tape specifications. Ensure the ordering quantity aligns with the factory reel size requirements. Confirm RoHS compliance status through the provided documentation before finalizing procurement. Cross-reference the part number with the latest Toshiba Semiconductor catalog to avoid obsolete stock.

Selection Notes

Select this component when designing circuits that require four separate brushed motor channels with moderate current demands. The QFN-48 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 1.3 W power dissipation limit and implement appropriate thermal management strategies if operating near maximum load conditions.

Part Context

This integrated circuit belongs to Toshiba's series of brushed DC motor driver ICs designed for general-purpose motion control. It integrates the necessary power stages and control logic into a single CMOS-based solution. The device simplifies system design by reducing the component count required for multi-axis motor applications compared to discrete solutions.

Replacement Considerations

Consult Toshiba's official cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains compatibility with the 38 V supply voltage and 3.5 A output current requirements. Verify pinout and package dimensions match the existing QFN-48 layout to prevent mechanical integration issues.
