TB67H301FTG,EL

Overview

The TB67H301FTG,EL is a dual DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates two high-current output channels capable of driving motors up to 2.5A continuous current per channel with peak currents reaching 4.0A. The device features an integrated bootstrap circuit for high-side N-channel MOSFET drive, eliminating the need for external bootstrap diodes or capacitors in many configurations. It supports PWM speeds up to 100kHz and includes protection functions such as overcurrent detection, thermal shutdown, and short-circuit protection. The component operates within a supply voltage range of 4.5V to 18V.

Feature Summary

• Integrated dual H-bridge architecture with built-in bootstrap functionality for simplified power stage design
• Comprehensive protection mechanisms including overcurrent sensing, thermal shutdown, and short-to-ground/short-to-VCC detection
• Supports multiple control modes including full-step, half-step, and microstep driving via simple logic inputs

Applications

• Industrial automation equipment requiring precise motor control
• Office automation devices such as printers and copiers
• Home appliances featuring fan or pump motor regulation

Procurement Notes

Verify the exact suffix 'EL' against official Toshiba documentation to confirm tape-and-reel packaging specifications and environmental compliance status. Ensure that the ordering code matches the specific temperature grade and pin configuration required for your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with your system's voltage and current requirements before finalizing procurement.

Selection Notes

Select this component when a compact solution for driving two DC motors is required without external discrete MOSFETs. It is suitable for applications needing moderate current levels up to 2.5A per channel. Consider the thermal performance and heat dissipation requirements of the VQFN package. Verify that the input logic levels are compatible with the controlling microcontroller or FPGA signals.

Part Context

This part belongs to Toshiba's TB67 series of motor drivers, designed for cost-effective and space-saving motor control solutions. The TB67H301 specifically targets applications requiring dual-channel control in a small footprint. It competes with other dual H-bridge drivers offering similar current ratings and integrated protection features.

Replacement Considerations

Check for direct replacements like the TB67H301AFG if different packaging is needed. Verify pin-to-pin compatibility with alternative dual H-bridge drivers from other manufacturers only after confirming electrical parameter equivalence and thermal characteristics.
