TB67H481FTG(O,EL)

Overview

The TB67H481FTG(O,EL) is a BiCD constant current dual H-bridge driver IC designed for brushed motor applications. It features two independent channels, each capable of delivering up to 2.5A output current with a maximum supply voltage of 50V. The device supports clock input control and operates within a temperature range of -40°C to +85°C. Packaged in a compact VQFN-32 5x5mm format, it integrates power and control stages for efficient motor management.

Feature Summary

• Dual-channel H-bridge architecture for independent motor control
• Integrated constant current control functionality
• Clock input interface for simplified drive signals
• Compact surface-mount packaging for space-constrained designs

Applications

• Brushed DC motor drives
• Small appliance motor control
• Industrial automation actuators
• Robotics joint control systems

Procurement Notes

Verify the specific suffix (O, EL) against the manufacturer's official datasheet to confirm tape-and-reel specifications and environmental compliance status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the electrical parameters with your system requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual-channel brushed motor control with integrated constant current regulation is required. The VQFN-32 package suits applications needing high pin density in limited board area. Consider the 50V voltage rating and 2.5A per channel capability to ensure adequate headroom for your specific motor load and supply conditions.

Part Context

This part belongs to Toshiba's TB67H series of brushed motor driver ICs. The series focuses on integrating power MOSFETs and control logic into single packages. This specific model emphasizes dual-channel operation with clock input compatibility, distinguishing it from PWM-only or single-channel variants in the broader product family.
