Overview
The KA9258BD is a CD Motor Driver manufactured by Fairchild Semiconductor, housed in a 28-pin SSOP package with dimensions of 0.375 inches and an integrated heat sink. It operates as a single-function interface IC designed for motor control applications. The component utilizes a plastic/epoxy body with a rectangular small outline form factor featuring a shrink pitch and exposed heat sink slug. It complies with RoHS standards and carries JESD-609 code e3, indicating lead-free termination. The device is classified under humidity sensitivity level 1 and is suitable for surface mount assembly processes.
Feature Summary
- Integrated heat sink design for enhanced thermal management
- RoHS compliant construction with lead-free terminations
- Single-function motor driver interface capability
Applications
- Motor control systems requiring integrated thermal dissipation
- Interface circuits for CD mechanisms
- Applications utilizing SSOP-28 surface mount technology
Procurement Notes
Verify the specific suffix against official Fairchild documentation to confirm exact pinout and thermal characteristics. Ensure the procurement source provides valid datasheets confirming the SSOP-28 package with heat sink slug. Cross-reference the manufacturer part number to distinguish between standard and specialized variants within the KA9258 series.
Selection Notes
Select this component when a dedicated motor driver with built-in thermal sinking is required in a compact SSOP-28 footprint. Consider the 0.375-inch package width for PCB layout constraints. Verify compatibility with the target motor voltage and current requirements against the official electrical specifications provided in the manufacturer's datasheet.
Part Context
This component belongs to the Fairchild Semiconductor analog mixed-signal IC portfolio, specifically within the drivers and interface category. It is designed for applications requiring reliable motor control integration. The product line emphasizes compact packaging solutions with thermal efficiency for consumer electronics and industrial interface modules.
Replacement Considerations
Consult official Fairchild substitution guides for direct equivalents. Verify pin-to-pin compatibility and thermal performance metrics before replacing with alternative motor driver ICs from other manufacturers.
