TB67H401FTG,EL

Overview

The TB67H401FTG,EL is a BiCDMOS dual full bridge motor driver IC designed for controlling brushed DC motors. It operates within a supply voltage range of 4.75V to 5.25V and supports load voltages up to 48V. The device features constant current control via PWM, supporting CW, CCW, short brake, and stop modes with an integrated standby function. Packaged in a 48-pin VQFN (7x7mm) format with an exposed pad, it is optimized for applications requiring precise motor management.

Feature Summary

• Supports constant current control using PWM signals for precise motor regulation
• Enables multiple operational modes including clockwise, counter-clockwise, short brake, and stop
• Integrates a standby function to reduce power consumption during idle periods

Applications

• Brushed DC motor control systems
• Automotive interior devices
• Office automation equipment
• Industrial control modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape/reel specifications. Confirm that the required operating temperature range aligns with the component's rated limits. Cross-reference the part number with the latest Toshiba Semiconductor datasheet to validate pinout compatibility and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a dual H-bridge configuration is required for bidirectional brushed DC motor control. It is suitable for designs needing integrated constant current regulation and low-power standby capabilities. Ensure the system logic levels are compatible with the PWM input requirements. Consider the thermal performance of the 48-VQFN package relative to the expected continuous current load and ambient operating conditions.

Part Context

This component belongs to the TB67H series of motor drivers from Toshiba Semiconductor and Storage. The series utilizes BiCDMOS technology to integrate control logic and power stages. This specific model provides dual channel output capability, distinguishing it from single-channel variants in the lineup while maintaining similar interface protocols and protection features.

Replacement Considerations

Consult official Toshiba substitution lists for verified equivalents. Generic replacements may not match the BiCDMOS integration or specific standby functionality.
