PTC PT2511
The PT2511 is a three-phase, hall sensor sinusoidal brushless DC motor driver with integrated power MOSFETs, which can provide continuous drive current up to 1.5A. The three-phase control is based on sine wave driving scheme and it is designed to reduce electrical audible noise in motor phase commutation. The integrated charge pump of the device boosts VDD internally and fully enhances the high-side MOSFETs.| Part No. | PT2511 |
