TDA5141 Description
TDA5141 The TDA5141 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-EMF sensing technique to sense the rotor position. It is ideally suited for applications requiring powerful output stages (minimum current limit of 1.9 A).
TDA5141 Key Features
- Full-wave mutation (using push/pull drivers at the output stages) without position sensors
- Built-in start-up circuitry
- Three push-pull outputs
- output current 1.9 A (typ.)
- low saturation voltage
- built-in current limiter
- Thermal protection
- Flyback diodes
- Tacho output without extra sensor
- Position pulse stage for phase-locked-loop control
