TA7291SG(O,J)

Overview

The TA7291SG(O,J) is a bridge driver integrated circuit manufactured by Toshiba Semiconductor and Storage, designed for brush DC motor control applications. The device operates within a supply voltage range of 12V to 18V and supports a maximum output current of 1.2A. It is housed in a SIP-9 package with dimensions of 22.28mm length. The component functions reliably across an operating temperature range from -30°C to 75°C.

Feature Summary

• Integrated H-bridge architecture for bidirectional DC motor control
• Built-in protection mechanisms against overcurrent conditions
• Direct interface compatibility with standard logic families

Applications

• Brushed DC motor speed regulation systems
• Bidirectional motor direction control circuits
• Automotive accessory drive modules

Procurement Notes

Verify the specific suffix (O or J) against the manufacturer's official datasheet to confirm pinout configuration and thermal characteristics. Ensure the selected variant matches the required operating temperature range and packaging specifications for your design. Cross-reference the RoHS compliance status as indicated in the component documentation.

Selection Notes

Select this component when a compact solution for low-power brushed DC motor driving is required. The SIP-9 package offers through-hole mounting convenience. Consider the 1.2A current limit and 18V maximum supply voltage when sizing the power stage. Verify that the logic input levels are compatible with the system microcontroller or controller IC.

Part Context

This part belongs to Toshiba's bridge driver series, specifically engineered for small to medium power DC motor applications. It integrates the necessary power switches and control logic into a single package, reducing board space and simplifying the design process for motor control systems compared to discrete solutions.

Replacement Considerations

Consult official Toshiba substitution lists for direct equivalents. Generic replacements may differ in pinout or internal protection features. Verify thermal resistance and current handling capabilities before substituting.
