TB67H453FNG(O,EL)

Overview

The TB67H453FNG(O,EL) is a brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It features an integrated H-Bridge configuration with two half-bridge outputs capable of delivering up to 3.5 A continuous output current. The device supports a supply voltage range from 4.5 V to 44 V and handles load voltages up to 50 V. Packaged in a 16-pin HTSSOP (TSSOP) surface-mount format, it operates within a junction temperature range of -40°C to +150°C and an ambient temperature range of -40°C to +85°C. The component includes built-in current monitoring functions for enhanced system control.

Feature Summary

• Integrated H-Bridge architecture providing dual half-bridge outputs for complete brushed DC motor control
• Built-in current monitoring function enabling real-time feedback and protection capabilities
• High thermal performance supporting operation up to a 150°C junction temperature

Applications

• Brushed DC motor control systems
• Motion control applications requiring integrated drive and monitoring
• Industrial automation equipment

Procurement Notes

Verify the exact suffix designation when ordering, as variations such as EL or O,EL may indicate specific tape-and-reel packaging configurations or regional compliance standards. Confirm that the HTSSOP-16 footprint matches your PCB layout requirements. Ensure the design accommodates the specified thermal dissipation limits given the 2.5 W power dissipation rating under typical operating conditions.

Selection Notes

Select this component when a single-chip solution is required for driving brushed DC motors with integrated current sensing. It is suitable for designs needing a wide input voltage range up to 44 V. Compare against the TB67H450 series if a smaller 8-pin package is preferred, noting that the TB67H453 offers higher pin count for additional functionality or thermal management.

Part Context

This part belongs to Toshiba's TB67H4xx series of brushed motor drivers. It shares functional similarities with the TB67H450 and TB67H451 but distinguishes itself through the H-Bridge topology and current monitoring integration. The series targets general-purpose motor drive applications where compact size and integrated protection features are prioritized over discrete component solutions.

Replacement Considerations

The TB67H450FNG(EL) serves as a related alternative within the same product family, though it utilizes an 8-pin HSOP package and lacks the full H-Bridge configuration found in the TB67H453.
