TB67S581FNG Image

The TB67S581FNG from Toshiba is a Two-Phase Constant-Current Bipolar Stepping Motor Driver IC that has been designed for precision motor control applications. It requires an input voltage of 8.2 - 44 V. This motor driver sets a new benchmark in stepping motor driver technology by utilizing the advanced BiCD process, delivering exceptional performance and versatility for a wide range of applications. It provides a variety of features to enhance motor control capabilities, including the ability to select between mixed decay, slow decay, and fast decay modes based on specific operational requirements. This motor driver offers flexible clock input control for precise synchronization with external devices, and simplifies power supply configurations with its built-in 3.3 V regulator output, thereby allowing single (motor voltage) VM power supply operation. It enables optimal control and smooth motion through its support for multiple-step operation modes, including full, half, quarter, 1/8, 1/16, and 1/32 steps.

This motor driver incorporates integrated safety features like thermal shutdown detection (TSD), over-current detection, and under-voltage lockout detection (UVLO), guaranteeing a reliable and secure operation. It also features an error detection flag output function (nFAULT) to simplify troubleshooting and enhance system integration functionalities. This RoHS-compliant motor driver simplifies system integration and reduces costs by minimizing the need for external components through optimized charge pump utilization, streamlining the overall design. It is available in a surface-mount package that measures 9.7 x 6.4 mm.
