TB67S101ANG

Overview

The TB67S101ANG is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates control logic and power MOSFETs in a single package. The device supports step resolutions of full, half, and quarter steps. It operates with a supply voltage range of 4.75V to 5.25V and handles load voltages from 10V to 47V. The output current capability is rated at 4A. It features an HTSSOP-48 or SDIP-24 package depending on the specific suffix variant, though the ANG designation typically corresponds to the through-hole SDIP-24 form factor. Operating junction temperature ranges from -20°C to 150°C.

Feature Summary

• Integrates control circuits and power MOSFETs for bipolar stepper motors
• Supports full, half, and quarter step resolution modes
• Includes protection functions such as under-voltage lockout, over-current detection, and thermal shutdown

Applications

• Bipolar stepper motor control systems
• Industrial automation equipment
• Office automation devices

Procurement Notes

Verify the exact package type (SDIP-24 vs HTSSOP-48) against the specific datasheet revision, as naming conventions may vary. Confirm the manufacturer is Toshiba Semiconductor and Storage. Ensure the application environment stays within the specified voltage and current limits. Check for moisture sensitivity levels if lead-free processing is required. Validate that the 4A rating aligns with your thermal management design.

Selection Notes

Select this component when driving bipolar stepper motors requiring integrated control and power stages. It is suitable for applications needing multiple step resolutions without external logic. Consider the through-hole SDIP-24 package for easier prototyping or high-reliability mounting. Ensure the load voltage does not exceed 47V and the supply voltage remains within 4.75V to 5.25V. Verify thermal requirements for continuous 4A operation.

Part Context

This part belongs to the TB67S101 series of stepping motor driver ICs from Toshiba. The series includes variants like TB67S101AFG and TB67S101AFTG, which differ primarily in packaging. The ANG variant specifically denotes the 24-SDIP through-hole package. These drivers are designed for general-purpose bipolar stepper motor applications, offering a compact solution compared to discrete driver designs.

Replacement Considerations

Direct substitutes include other parts from the same TB67S101 family, such as TB67S101AFG or TB67S101AFTG, provided the package difference is acceptable. Cross-brand replacements require careful verification of pin compatibility, voltage ratings, and current capabilities.
