FAN8413MX

Overview

The FAN8413MX is a two-phase half-wave brushless DC (BLDC) motor predriver manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4V to 28V. The device integrates locked rotor protection mechanisms, featuring an open-collector alarm output or speed signal output alongside automatic retry functionality upon fault clearance.

Feature Summary

• Supports two-phase half-wave BLDC motor control architectures
• Integrates locked rotor detection with auto-retry capability
• Provides diagnostic feedback via open-collector alarm or speed output

Applications

• Fan controller applications
• Brushless DC motor drive systems
• HVAC fan speed regulation

Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor has been acquired by ON Semiconductor. Ensure the specific suffix matches your board design requirements and confirm RoHS compliance status for current production units. Cross-reference pinouts if substituting from other vendors.

Selection Notes

Select this component for simple two-phase half-wave BLDC applications requiring integrated protection. It is suitable where low component count is prioritized over complex commutation algorithms. Verify that the motor type aligns with the half-wave topology constraints before implementation.

Part Context

This part belongs to the FAN841x series of motor controllers. It is functionally related to the FAN8412MX but differs in specific internal configuration or feature set. The series targets cost-sensitive fan control markets requiring robust startup and stall protection without external microcontrollers.

Replacement Considerations

The FAN8413MX-G is noted as a direct pin-to-pin replacement option due to matching internal reference voltages. Verify package compatibility and electrical specifications when considering alternative sources from Rochester Electronics or ON Semiconductor.
