TB62206FG,EL

Overview

The TB62206FG,EL is a BiCD PWM two-phase bipolar stepping motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates DMOS parallel output stages capable of driving loads up to 1.5A per phase. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 20-HSOP package. Key internal features include an integrated chopper circuit for current control, thermal shutdown protection, and short-circuit detection mechanisms to ensure reliable operation in stepper motor applications.

Feature Summary

• Integrates a chopper circuit for precise constant current control of bipolar stepper motors
• Includes built-in thermal shutdown and short-circuit protection circuits for enhanced reliability
• Utilizes BiCD technology combining bipolar and CMOS processes for efficient power management

Applications

• Bipolar stepper motor drive systems
• Office automation equipment requiring precise motion control
• Industrial automation modules utilizing small to medium torque motors

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with the required 4.5V to 5.5V operating voltage range. Confirm that the 20-HSOP footprint matches the target PCB design. Cross-reference the part number with the latest datasheet revision to validate pinout and electrical characteristics before integration.

Selection Notes

Select this component when a dedicated driver for bipolar stepper motors is required with integrated current chopping and protection features. It is suitable for applications demanding a compact solution with low external component count. Consider the 1.5A per phase limit and 5.5V maximum supply voltage constraints during system design. Verify thermal requirements based on expected load currents and ambient conditions.

Part Context

This part belongs to Toshiba's Bipolar Stepping Motor Drivers family, specifically designed for BiCD PWM applications. It serves as a specialized motor control solution distinct from general-purpose logic or linear drivers. The product line focuses on integrating power stages and control logic to simplify motor interface designs in consumer and industrial electronics.

Replacement Considerations

Consult official Toshiba substitution guides for verified alternatives. Generic replacements may lack compatible pinouts or protection features. Ensure any substitute supports the same bipolar stepper motor topology and voltage range.
