Description
The TDA5145TC1DB is a bipolar integrated circuit designed for driving 3-phase brushless DC motors in full-wave mode. It is a sensorless device that uses back-EMF sensing to detect the rotor position. The TDA5145TC1DB features bidirectional control, a brake function, and a built-in circuit to reduce EMI (Electromagnetic Interference).
Specifications and features
- Full-wave commutation without the need for position sensors.
- Built-in start-up circuitry.
- Three push-pull outputs with a current limiter and soft-switching for low EMI.
- Thermal protection and flyback diodes.
- Tacho output without the need for an extra sensor.
- Motor brake facility and direction control input.
- Reset function and a transconductance amplifier for external control.
Application Scenarios
- General purpose spindle driver for hard disk drives, tape drives, and optical disk drives.
Comparison
Advantages- Sensorless design, eliminating the need for three hall-sensors.
