TDA5142T Datasheet (NXP) - Brushless DC motor drive circuit

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
