FAN8100N

Overview

The FAN8100N is a low voltage, low saturation two-channel DC motor driver manufactured by Fairchild Semiconductor. It utilizes bipolar technology to provide an output current of 3A per channel. The device operates with a supply voltage range of 2.2V to 9V and supports load voltages from 1.8V to 9V. It functions within an operating temperature range of -20°C to 75°C (TA). This component is designed for driving brushed DC motors in general-purpose applications.

Feature Summary

• Two-channel architecture for independent control of dual motors
• Low saturation design for efficient power management
• Bipolar technology implementation for robust output drive

Applications

• Brushed DC motor control systems
• General purpose motor driver circuits
• Low voltage electronic devices requiring dual motor actuation

Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm package compatibility with existing PCB layouts, specifically the 12-DIP configuration. Ensure supply chain sources are authorized distributors capable of handling legacy components. Validate that the 3A output current meets system requirements without additional thermal management solutions beyond standard DIP dissipation capabilities.

Selection Notes

Select this component when a dual-channel solution is required for brushed DC motors operating within the specified voltage limits. The 12-DIP package suits through-hole assembly processes. Consider the bipolar technology characteristics for drive strength needs. Verify that the ambient temperature range of -20°C to 75°C aligns with the target environment constraints.

Part Context

This component belongs to the FAN8100 series of motor drivers and controllers. It falls under the PMIC category specifically designated for motor control applications. The manufacturer transitioned from Fairchild Semiconductor to ON Semiconductor, affecting lifecycle documentation but maintaining technical specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require functional equivalence analysis rather than pin-to-pin substitution.
