Overview
The BD62012BFS-E2 is a 3-phase brushless fan motor controller manufactured by ROHM Semiconductor. It operates on a supply voltage range of 10 V to 18 V, with a maximum rating of 18 V and a collector-emitter voltage of 50 V. The device features an output current capability of 15 mA and a working supply current of 2.5 mA. It provides four outputs at 5 V. Designed for surface mount installation in an SSOP-A-24 package, it functions within a temperature range of -40°C to +110°C.
Feature Summary
- Synthesizes optimal driving signals from Hall sensor inputs for three-phase brushless fan motors
- Integrates Power MOSFET technology for efficient motor control
- Supports surface mount assembly in compact SSOP-A-24 packaging
Applications
- Three-phase brushless fan motor control systems
- Computer cooling fans
- Server and data center ventilation units
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. Ensure the SSOP-A-24 footprint matches the target PCB design. Confirm that the 15 mA output current meets the load requirements of the intended brushless fan application before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring integrated control for three-phase brushless DC fans. The low operating supply current of 2.5 mA supports energy-efficient designs. Verify that the input signal interface aligns with the available Hall sensor outputs in the system architecture. The wide operating temperature range ensures reliability in varied thermal environments.
Part Context
This part belongs to ROHM's Motor / Motion / Ignition Controllers & Drivers category, specifically under Brushless DC Motor Controllers. It is classified as a PMIC - Power Management IC designed for motion control applications. The device utilizes Power MOSFET technology to manage motor phases directly from sensor inputs.
Replacement Considerations
The BD2601XBFS is identified as a related three-phase brushless fan motor controller from the same manufacturer family. Verify electrical specifications and pin compatibility before substitution.
