FAN8024CDTFQ

Overview

The FAN8024CDTFQ is a monolithic integrated circuit designed as a four-channel motor driver. It is suitable for driving two-channel bridge-tied load (BTL) DC motors or two-channel motor drivers with current feedback, commonly used in optical drive mechanisms for focus and tracking applications. The device integrates high-side and low-side drivers to control external power MOSFETs.

Feature Summary

• Integrates gate drive circuitry for external N-channel power MOSFETs
• Supports bridge-tied load configurations for efficient DC motor control
• Includes protection features against shoot-through conditions

Applications

• Optical disk drive focus and tracking mechanisms
• Two-channel BTL DC motor driver circuits
• Motor drivers requiring current feedback integration

Procurement Notes

Verify the specific suffix 'TFQ' against official Fairchild/ON Semiconductor documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with existing PCB footprints and thermal management requirements for the SOIC-16 package before procurement.

Selection Notes

Select this component when designing compact motor control stages for optical drives. It simplifies layout by integrating driver logic and protection functions. Verify that external MOSFET selection matches the voltage and current ratings required by the specific motor application.

Part Context

This part belongs to the FAN8024 family of motor driver ICs from Fairchild Semiconductor. These devices are engineered for high reliability in consumer electronics, particularly in storage devices where precise motor positioning is critical. The technology leverages CMOS processes for low power consumption.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Cross-reference with ON Semiconductor equivalents if Fairchild inventory is unavailable. Ensure electrical specifications match exactly to avoid redesigning the external MOSFET stage.
