TB6559FG,8,EL

Overview

The TB6559FG,8,EL is a full-bridge DC motor driver IC designed for brushed DC motors. It integrates LD-MOS output transistors and supports a supply voltage range of 10V to 30V with a continuous output current of 1A. The device operates within an ambient temperature range of -30°C to 85°C. It utilizes a 16-HSOP package with exposed pad for thermal management. Control inputs IN1 and IN2 enable four distinct operational modes: clockwise rotation, counter-clockwise rotation, short brake, and stop.

Feature Summary

• Integrates LD-MOS output transistors for efficient power handling in a full-bridge configuration.
• Supports four control modes including forward, reverse, short brake, and stop via simple logic inputs.
• Features integrated thermal shutdown protection to safeguard the device during overload conditions.

Applications

• Brushed DC motor control in office automation equipment
• Motor drive circuits in home appliances
• Industrial control systems requiring low-power motor actuation

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel quantity or cut tape format. Confirm the package variant corresponds to the 16-HSOP specification with the exposed thermal pad. Ensure the component status is active for long-term production planning. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a single-chip solution for brushed DC motor direction and braking is required. It is suitable for applications needing a 1A current capacity within a 10V to 30V supply range. Consider the 16-HSOP package constraints for PCB layout and thermal dissipation requirements compared to higher current alternatives.

Part Context

This part belongs to the Toshiba TB6559 series of motor drivers. It is specifically engineered for general-purpose brushed DC motor applications. The series emphasizes integration by combining control logic and power stages into a single compact package, reducing external component count and board space.

Replacement Considerations

Check for direct pin-compatible substitutes within the Toshiba TB655x family. Verify electrical parameters such as voltage rating and current capacity against alternative vendors' offerings. Ensure package dimensions and thermal characteristics match the existing design constraints before substitution.
