The DRV11873 from Texas Instruments is a 3-phase, sensorless Brushless DC (BLDC) motor driver. It is specifically engineered for fan motor drive applications, offering a low noise profile and minimal external component requirements.
This driver integrates power MOSFETs capable of delivering up to 1.5-A continuous output current and 2-A peak current. It operates with an input voltage range of 5 V to 16 V. The device utilizes a proprietary BEMF control scheme for sensorless operation and synchronous rectification for increased efficiency.
Key features include built-in overcurrent protection, lock detection, voltage surge protection, UVLO, and thermal shutdown. The DRV11873 provides FG and RD open-drain outputs for motor status indication. It is housed in a thermally-efficient 16-pin TSSOP package, suitable for surface mount applications.
Applications for the DRV11873 include appliance cooling fans, desktop cooling fans, and server cooling fans, where reliable and efficient motor control is essential.
