Overview
The FAN8404DTF is a monolithic integrated circuit designed as a two-phase half-wave brushless DC (BLDC) motor driver. It operates within a wide input voltage range up to 15V and integrates essential control functions for polygon mirror motors used in laser beam printers. The device features built-in protection mechanisms, including a motor lock detector, to ensure reliable operation under varying load conditions.
Feature Summary
- Integrated two-phase half-wave BLDC motor drive capability
- Built-in motor lock detection mechanism
- Wide operating voltage range supporting up to 15V
Applications
- Polygon mirror motor drivers in laser beam printers
- Brushless DC motor control systems requiring two-phase half-wave topology
- Optical scanning equipment utilizing BLDC actuators
Procurement Notes
Verify the manufacturer source carefully, as Fairchild Semiconductor's semiconductor division was acquired by ON Semiconductor. Ensure the datasheet corresponds to the specific FAN8404 variant. Confirm RoHS compliance status and lead-free packaging requirements with the supplier before procurement.
Selection Notes
Select this component specifically for applications requiring a dedicated two-phase half-wave BLDC driver. It is suitable for low-to-medium power polygon mirror motors where integrated lock detection is beneficial. Evaluate if the 15V maximum input voltage aligns with the system power supply constraints.
Part Context
This part belongs to the FAN84xx series of motor drivers from Fairchild Semiconductor (now ON Semiconductor). The series includes variants like the FAN8400D for similar printer applications. These ICs are specialized for driving small BLDC motors found in office automation equipment.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family, such as other FAN84xx variants. Verify functional equivalence regarding phase configuration and voltage ratings when considering alternative manufacturers.
