TDA5145TS
Datasheet
General description
The TDA5145TS 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 includes bidirectional control, brake function and has a special circuit built-in to reduce the EMI (soft-switching output stages).
Features
- Full-wave commutation (using push-pull drivers at the output stages) without position sensors
- Built-in start-up circuitry
- Three push-pull outputs:
- Output current 2.0 A (typ.)
- Built-in current limiter
- Soft-switching outputs for low Electromagnetic
- Interference (EMI).
- Thermal protection
- Flyback diodes
- Motor brake facility
- Direction control input
- Reset function.
