TDA5145 Datasheet (NXP) - Brushless DC motor drive circuit

TDA5145, Brushless DC motor drive circuit

APPLICATIONS * General purpose spindle driver e.g.: * Hard disk drive * Tape drive * Optical disk drive.

TDA5145 The TDA5145 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-senso

TDA5145 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 Electroma
