DRV10974PWPR +BOM

12-V nominal, 2.5-A peak sensorless sinusoidal control 3-phase BLDC motor driver

DRV10974PWPR General Description

For applications requiring precise speed control, the DRV10974PWPR offers a reliable and feature-rich solution. With a supply voltage range of 8V to 36V and the ability to deliver up to 2.3A of continuous current per phase, this three-phase sensorless motor driver IC is well-suited for robotics, drones, and industrial equipment. Its integrated protection circuitry, including overcurrent and thermal protection, ensures safe operation of the motor system, while the built-in diagnostic features, such as open load detection and stall detection, enhance system reliability. The DRV10974PWPR's advanced sensorless control algorithm enables accurate motor speed and position control without the need for external position sensors, simplifying system design and reducing overall component count. Additionally, its small footprint and thermally enhanced package make it ideal for space-constrained applications. With its versatility and advanced features, the DRV10974PWPR is a popular choice for a wide range of motor control applications
