Description
The TIDA-01619 provides a three-phase brushless DC (BLDC) motor driver solution for systems that have operating range from 4.4 V to 18 V.
This design features the DRV10974 motor driver with the ability to add MCU for closed loop speed control. The DRV10974 offers sensorless commutation with no need of hall sensors, only 6 external passive components allow for a low-cost solution, and an 180° sinusoidal commutation system allows optimal efficiency and low acoustics.
This reference design provides guidelines in 22-mm diameter board design and thermal enhancement with a double-layer layout and 2-oz copper thickness.
Features
- Thermally Enhanced: 2 layers and 2 oz copper thickness
- Small Form Factor: 22 mm diameter
- Low acoustics
- Ability to add MCU for closed loop speed control
- Fully protected realized by on-chip protection from 10974
