TB67S521FTAG,EL

Overview

The TB67S521FTAG,EL is a fully integrated bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a half-bridge configuration with two output channels capable of delivering up to 2.8 A per phase. The device operates within a load voltage range of 10 V to 34 V and supports PWM frequencies up to 100 kHz. Designed for surface-mount installation, it utilizes a WQFN-36 package with a maximum height of 0.75 mm. The IC functions within an ambient temperature range of -20°C to +85°C and requires a supply voltage between 2 V and 5.5 V.

Feature Summary

• Fully integrated control and power stage for precise stepping motor operation
• Supports high-frequency PWM input signals for accurate speed and position control
• Compact surface-mount design suitable for space-constrained applications

Applications

• Precision positioning systems in industrial automation equipment
• Motion control modules for office automation devices
• Actuator drivers in medical instrumentation requiring compact form factors

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm packaging and tape specifications. Ensure compatibility with the target PCB footprint for the WQFN-36 package. Confirm thermal management requirements align with the specified power dissipation limits under expected operating conditions.

Selection Notes

Select this component when a single-chip solution for bipolar stepper motors is required. It is suitable for applications needing moderate current drive up to 2.8 A without external power transistors. Consider the operating voltage range and thermal performance relative to the enclosure environment.
