TB67H453FTG(O,EL)

Overview

The TB67H453FTG(O,EL) is a single-channel H-bridge driver for brushed DC motors manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 4.5 V to 44 V and delivers an output current of 3.5 A with a maximum load voltage of 50 V. The device features integrated current monitoring via the ISense pin and supports PWM frequencies up to 100 kHz. It is housed in a compact QFN16 (3x3 mm) package suitable for surface mount installation. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a single H-bridge configuration with dedicated current monitoring functionality accessible through the ISense output pin.

Applications

• Brushed DC motor control systems
• Industrial motion control applications

Procurement Notes

Verify the specific suffix (O,EL) against official Toshiba documentation to confirm packaging and material specifications. Ensure compatibility with the target PCB footprint for the QFN16 package. Confirm that the application environment remains within the specified thermal and voltage limits to maintain device reliability.

Selection Notes

Select this component when a single-channel solution with built-in current sensing is required. The QFN16 package offers a small form factor compared to larger alternatives. Consider the 3.5 A continuous current rating and 50 V blocking voltage when sizing for the intended motor load.

Part Context

This part belongs to the TB67H series of brushed motor drivers from Toshiba. It provides a specialized solution for applications requiring precise motor control with diagnostic feedback capabilities. The integration of the H-bridge and monitoring circuitry reduces external component count.

Replacement Considerations

Consult official Toshiba substitution guides for verified equivalents. Cross-reference electrical parameters such as output current, voltage ratings, and package dimensions before considering alternative manufacturers.
