| Part Number | TDA5144 |
| Manufacturer | NXP (https://www.nxp.com/) |
| Description | The TDA5144 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 sen... |
| 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.) – low saturation voltage – built-in current limiter – soft-switching outputs for low Electromagnetic Interference (EMI) • Thermal protection • Flyback diodes • Tacho output without extra sensor • Transconductance amplifier for an external control transistor. QUICK REFERENCE DATA Measured over full voltage and temperature range. SYMBOL VP VVMOT VDO ILIM Notes 1. An unstabilized supply can be used. 2. VVMOT = VP; +A... |
