TB6561NG

Overview

The TB6561NG is a fully integrated DC motor driver and controller manufactured by Toshiba Semiconductor and Storage. It utilizes Bi-CMOS technology to provide four half-bridge outputs capable of driving brushed DC motors. The device supports PWM interface control and operates within a supply voltage range of 10V to 36V, delivering an output current of 1.5A per channel. It is housed in a 24-pin SDIP package designed for through-hole mounting. The component functions as a complete drive system, integrating both control logic and power stages.

Feature Summary

• Fully integrated driver with combined control and power stages
• Four-channel half-bridge output configuration
• Supports PWM interface for motor control
• Bi-CMOS technology implementation

Applications

• Brushed DC motor control systems
• General industrial automation applications
• Consumer electronic devices requiring motor drive

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates the packaging type. Confirm the manufacturing status, as availability may vary between active production and end-of-life phases. Ensure the selected package variant matches the required PCB mounting style. Cross-reference the exact part number with official distributor catalogs to confirm current stock levels and lead times before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a single-chip solution for brushed DC motor management. The through-hole SDIP package is suitable for prototyping or designs prioritizing mechanical robustness over board space. Consider the 1.5A current rating and 36V maximum voltage limit to ensure compatibility with the target motor specifications. Verify thermal management requirements based on the expected load conditions and ambient temperature constraints.

Part Context

This part belongs to Toshiba's line of integrated motor drivers designed for simplicity and reliability. It replaces discrete solutions by combining gate drivers, logic, and protection circuits into one unit. The TB6561 series offers a cost-effective alternative for basic motor control needs without complex external components.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify that any substitute maintains the same voltage and current ratings. Ensure the replacement supports the required PWM control interface and package type.
