Overview
The TA7291P(O) is a bridge driver integrated circuit manufactured by Toshiba Semiconductor and Storage, designed for controlling the forward and reverse rotations of DC motors. It operates within a supply voltage range of 12 V to 18 V and supports a maximum output current of 1.2 A. The device functions as a brush DC motor controller and is housed in a SIP-9 package with dimensions of 22.28 mm length. It is rated for an operating temperature range from -30 °C to 75 °C.
Feature Summary
- Integrated full-bridge driver architecture for bidirectional DC motor control
- Supports forward and reverse rotation operations
- Designed for brush DC motor applications
Applications
- DC motor speed and direction control systems
- Automotive electronic components
- Industrial motor drive circuits
Procurement Notes
Verify the specific suffix (O) against official Toshiba documentation to confirm pinout compatibility and packaging variations. Ensure the component meets RoHS requirements if applicable, as some variants are marked non-compliant. Cross-reference the SIP-9 package details with the manufacturer's datasheet to validate physical dimensions and thermal characteristics before integration.
Selection Notes
Select this component for applications requiring a dedicated bridge driver for small to medium DC motors. Consider the 1.2 A current limit and 12–18 V supply range when designing power stages. Verify that the SIP-9 package fits the available PCB space and that the operating temperature range aligns with the environmental conditions of the target application.
Part Context
The TA7291 series includes variants such as the TA7291S and TA7291AF, offering different packaging options like SIP and SOP. These devices share the core functionality of bridge driving for DC motors. The TA7291P(O) specifically utilizes a SIP-9 package, distinguishing it from surface-mount alternatives while maintaining similar electrical performance characteristics for motor control tasks.
Replacement Considerations
Potential substitutes include other bridge drivers from Toshiba such as the TA7257P or TA7267BP. Verify electrical parameters and pin compatibility before substitution.
