Microchip Launches Sinusoidal, Sensorless, 3-Phase BLDC Fan Motor Driver

Microchip announces the expansion of its portfolio with the MTD6505, the industry’s first and only standalone, resistor-programmable driver that enables the selection of multiple back-EMF coefficient ranges.

 

This unique feature allows engineers to design for a wide variety of 3-phase BLDC fan characteristics with a single cost-effective and flexible device, thus saving time and money by standardising multiple product lines on one driver and very few external components. Additionally, the low-cost driver comes in a 3 x 3 mm UDFN package with a 0.5mm thickness for space-constrained applications.
To enable high energy efficiency and quiet operation with low acoustic noise and mechanical vibration, the MTD6505 includes a 180-degree sinusoidal drive. Being a sensorless driver means that the MTD6505 eliminates the need for an external Hall-Effect sensor, reducing both cost and board space.
The new MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board (ADM00345) is also available now for $59.99.
