TDA5140A Brushless DC Motor Circuit and Datasheet

[Amplifier] TDA5140A Brushless DC Motor Circuit and Datasheet: TDA5140A Scanner Driver Operational Transconductance Amplifier

The TDA5140A device is a bipolar integrated circuit which commonly used to draw 3-phase brushless DC motors in full-wave mode. This Brushless DC motor drive device is sensorless using the back-EMF sensing technique to sense the rotor position. This device used to be apply in applications such as VCR, laser beam printer, fax machine, blower, automotive.

The TDA5140A yet embody an Uncommitted Transconductance Amplifier (OTA) that can be appled as a control amplifier. The output is adequate for directly driving an external power transistor. The TDA5140A is built for systems with low current consumption, there are: use of I2L logic, adaptive base drive for the output transistors, likelihood of using a pick-up coil without bias current.

Brushless DC Motor Circuit can be completed in TDA5140A Datasheet.
