Overview
The BD62014FS-E2 is a 3-phase brushless fan motor controller manufactured by ROHM Semiconductor. It operates within a supply voltage range of 10 V to 18 V and supports output currents up to 30 mA. The device functions at frequencies between 16 kHz and 20 kHz, with a maximum power dissipation of 1 W. It features a low operating current of 2.8 mA and is housed in an SSOP-24 surface-mount package. The component is rated for operation across temperatures from -40 °C to +110 °C.
Feature Summary
- Designed specifically for controlling 3-phase brushless DC fans
- Integrates bipolar driver functionality driven by PWM current
- Supports surface-mount installation via SSOP-24 package
Applications
- 3-phase brushless fan motor control systems
- Low-power cooling applications requiring precise speed regulation
- Embedded motion control circuits with limited current requirements
Procurement Notes
Verify the NRND status before procurement, as this indicates the component is not recommended for new designs. Confirm that the SSOP-24 package aligns with existing PCB footprints. Ensure the 18 V maximum supply voltage and 30 mA output limits meet system requirements. Check RoHS compliance documentation if environmental regulations apply to the final assembly.
Selection Notes
Select this controller when a dedicated solution for 3-phase brushless fans is required within a 10 V to 18 V range. The low 2.8 mA operating current makes it suitable for energy-efficient designs. Consider the thermal constraints imposed by the 1 W power dissipation rating in enclosed environments. The wide temperature range supports industrial or automotive-grade deployments where stability from -40 °C to +110 °C is necessary.
Part Context
This part belongs to ROHM's Motor / Motion / Ignition Controllers & Drivers category under PMIC. It is distinct from general-purpose drivers, focusing on specialized 3-phase BLDC fan applications. The 'E2' suffix typically denotes specific packaging or compliance variations within the BD62014 family. It serves as a niche solution for small-scale rotational control rather than high-power industrial drives.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. The BD62014AFS-E2 shares similar specifications but may differ in pinout or electrical characteristics; verify datasheet compatibility before substitution. Due to the NRND status, alternative sourcing should prioritize components with active production status.
