TDA5142T - Brushless DC motor drive circuit
APPLICATIONS * High-power applications e.g.: * high-end hard disk drives * automotive.
TDA5142T The TDA5142T 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 s
