TDA5145 Datasheet - NXP

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
