TB67H450AFNG,EL

Overview

The TB67H450AFNG,EL is a single-channel brushed DC motor driver manufactured by Toshiba Semiconductor and Storage. It operates within a load voltage range of 4.5V to 44V and delivers an output current of 3.5A. The device supports forward, reverse, brake, and stop modes via IN1 and IN2 inputs. Key electrical parameters include a maximum supply voltage of 50V, a standby current of 1μA, and a power dissipation of 2.85W. It features integrated thermal shutdown (TSD), overcurrent protection (ISD), and undervoltage lockout (UVLO). The component is housed in an 8-HSOP package with a bottom heat pad.

Feature Summary

• Integrates low on-resistance MOSFETs for efficient PWM chopper control
• Provides comprehensive hardware protection including thermal shutdown and overcurrent detection
• Supports flexible input control for forward, reverse, brake, and stop operations
• Features built-in VCC regulator for stable internal circuit operation

Applications

• Robot vacuum cleaners and home cleaning appliances
• Electronic locks and access control systems
• Small household robots and automated devices
• Industrial equipment requiring single-motor drive

Procurement Notes

Verify the specific suffix EL against the manufacturer's latest documentation to confirm packaging type and tape specifications. Confirm that the part status remains appropriate for new designs, as availability may vary. Ensure the selected variant matches the required overcurrent recovery behavior, noting that this model typically requires manual reset after fault conditions.

Selection Notes

Select this component when a single-channel brushed DC motor driver with high current capability is required. It is suitable for applications needing wide voltage compatibility and robust protection mechanisms. Consider the TB67H451AFNG if automatic recovery from overcurrent faults is necessary instead of manual reset. Evaluate thermal management requirements due to the surface mount package design.

Part Context

This part belongs to the TB67H series of brushed DC motor drivers from Toshiba. The series utilizes BiCD process technology for high reliability. The TB67H450 variant specifically focuses on providing a locked-type protection mechanism, distinguishing it from auto-recovery models in the same family. It is designed for general-purpose motor control in consumer and industrial electronics.

Replacement Considerations

TB67H451AFNG,EL offers similar electrical characteristics but includes automatic recovery from overcurrent protection faults.
