TB6615PG,8

Overview

The TB6615PG,8 is a stepping motor driver IC manufactured by Toshiba Semiconductor and Storage. It is designed for unipolar stepper motors and brushless DC (BLDC) applications. The device integrates control and power stages in a fully integrated driver configuration. It operates within a supply voltage range of 2.7 V to 5.5 V. The component is housed in a 16-DIP package. It supports 1/4 step resolution and includes ISD protection features. The maximum load voltage rating is specified at 28 V with a current capacity of 0.4 A.

Feature Summary

• Fully integrated driver combining control logic and power stage functions
• Supports 1/4 step resolution for precise motor positioning
• Includes ISD protection mechanisms for enhanced reliability

Applications

• Unipolar stepping motor control systems
• Brushless DC (BLDC) motor drives
• Precision positioning devices requiring microstepping

Procurement Notes

Verify the specific suffix 'PG' against the manufacturer's official documentation to confirm pinout and thermal characteristics. Ensure the 16-DIP package footprint matches the target PCB design. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the active part status with current production schedules to avoid obsolescence risks during procurement.

Selection Notes

Select this component when a fully integrated solution for unipolar or BLDC motors is required. The 2.7 V to 5.5 V supply range suits low-voltage digital systems. The 16-DIP package facilitates prototyping and through-hole assembly. Consider the 0.4 A current limit and 28 V voltage rating for load compatibility. Verify that ISD protection meets system safety requirements.

Part Context

This part belongs to Toshiba's stepping motor driver series. It differs from bipolar drivers by supporting unipolar configurations. The integration reduces external component count compared to discrete solutions. The 16-DIP format offers accessibility for development environments. It serves as a dedicated controller-driver hybrid for small-scale motor applications.

Replacement Considerations

Check for direct substitutes with identical 16-DIP pinouts and 2.7-5.5 V operation. Verify matching current ratings of 0.4 A and voltage limits of 28 V. Ensure equivalent ISD protection levels. Confirm unipolar/BLDC compatibility before substitution.
