TB67S508FTG,EL

Overview

The TB67S508FTG,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a WQFN-36 surface-mount package and supports an output current of 3 A with a maximum supply voltage of 40 V. The device operates within a temperature range of -20°C to +85°C and includes four outputs. Key electrical parameters include a load voltage rating of 10 V to 38 V, a power dissipation of 4.3 W, and a working frequency of 70 kHz. The control circuit requires a supply voltage between 10 V and 35 V, drawing a typical operating current of 7 mA.

Feature Summary

• Integrates full control logic and power stages for bipolar stepper motors
• Supports multiple step resolution modes including half-step and quarter-step
• Includes built-in protection mechanisms against overcurrent and thermal overload

Applications

• Industrial automation equipment requiring precise motion control
• Office automation devices such as printers and scanners
• Security systems including surveillance camera pan-tilt mechanisms

Procurement Notes

Verify the specific suffix EL indicates the reel packaging configuration when placing orders. Confirm that the WQFN-36 package dimensions align with the target PCB footprint. Ensure the application design accounts for the specified 4.3 W power dissipation limits under expected load conditions. Check RoHS compliance documentation for regulatory requirements in the destination market.

Selection Notes

Select this component for applications requiring a 3 A drive capability with a 40 V voltage limit. The WQFN-36 package offers a compact solution for space-constrained designs. Consider the thermal performance characteristics given the 4.3 W dissipation rating. Verify compatibility with the required step resolution settings for the target motor type.
