TDA5140A - Brushless DC motor drive circuit
APPLICATIONS * VCR * Laser beam printer * Fax machine * Blower * Automotive.
TDA5140A The TDA5140A is a bipolar integrated circuit used to drive 3-phase brushless DC motors in full-wave mode.
The device is sensorless (saving of 3 hall-sensors) using the back
TDA5140A Features
* Full-wave commutation (using push/pull drivers at the output stages) without position sensors
* Built-in start-up circuitry
* Three push-pull outputs:
* 0.8 A output current (typ.)
* low saturation voltage
* built-in current limiter
* Thermal
