FAN8408DTF

Overview

The FAN8408DTF is a monolithic integrated circuit designed as a two-phase brushless DC motor controller. It operates within a supply voltage range of 4V to 15V and supports a load voltage up to 30V. The device delivers an output current of 1.2A and utilizes bipolar technology. Packaged in an 8-SOIC format with a width of 3.90mm, it is specifically engineered for driving DC cooling fan motors.

Feature Summary

• Monolithic integration suitable for DC cooling fan applications
• Wide operating voltage range from 4V to 15V
• Supports load voltages up to 30V

Applications

• DC cooling fan motors
• Brushless DC motor control systems

Procurement Notes

Verify component status as the FAN8408DTF is listed as discontinued by Fairchild Semiconductor. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing 8-SOIC footprints and validate that alternative sources provide genuine parts matching the original specifications.

Selection Notes

Select this component for low-power fan motor applications requiring integrated bipolar drive capabilities. Consider the 1.2A current limit and 30V load rating when designing power stages. The 8-SOIC package offers compact integration for space-constrained electronic designs targeting direct DC fan control.

Part Context

This part belongs to Fairchild's motor driver family, specifically tailored for fan applications. It integrates necessary drive circuits into a single chip, reducing external component count. The transition to ON Semiconductor may affect sourcing channels, though the technical specifications remain consistent with the original Fairchild design parameters.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify pin-to-pin compatibility with any potential alternatives before implementation.
