Overview
The KA3021D is a monolithic integrated circuit designed for DC motor control applications. It functions as a single-channel driver capable of forward and reverse operation, or as a three-channel driver specifically configured to actuate focus and tracking mechanisms in optical devices. The component operates within a supply voltage range of 4.5V to 13.2V. It is housed in a compact PDSO28 package, facilitating integration into space-constrained electronic systems requiring precise motor management.
Feature Summary
- Monolithic IC construction for reliable motor driving
- Supports single-channel forward/reverse DC motor control
- Capable of three-channel operation for focus and tracking actuators
Applications
- Focus actuator drive systems
- Tracking mechanism drivers
- Single-channel DC motor control circuits
Procurement Notes
Verify the manufacturer designation as Fairchild Semiconductor on all documentation. Confirm the specific package type is PDSO28. Ensure the part number matches exactly to avoid confusion with similar series components. Check datasheet revisions for any design changes before finalizing procurement specifications.
Selection Notes
Select this component when a compact solution for focus or tracking actuation is required. It is suitable for systems operating between 4.5V and 13.2V. Consider its capability to drive either one bidirectional channel or three distinct channels depending on the mechanical requirements of the target application.
Part Context
This device belongs to a family of motor driver ICs from Fairchild Semiconductor. Similar parts like the KA3027D2 share functional similarities but may differ in channel configuration or specific electrical ratings. The KA3021D is distinct in its suitability for optical focusing and tracking tasks.
Replacement Considerations
Consult official substitution lists for verified equivalents. Cross-reference pinouts and electrical characteristics carefully if considering alternative manufacturers. No direct substitute part numbers are confirmed in the provided public data.
