AMT49400 Description
The AMT49400 is an advanced 3-phase, sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs. A minimal application circuit can be achieved with only two external ponents due to device’s high level of integration, which includes control algorithm, analog circuit, and power stage. A field-oriented control (FOC) algorithm is fully integrated to achieve the best efficiency and acoustic noise...
