Overview: INTEGRATED CIRCUITS DATA SHEET TDA5142T Brushless DC motor drive circuit Product specification Supersedes data of March 1992 File under Integrated Circuits, IC11 June 1994 Philips Semiconductors Philips Semiconductors.

General Description

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 sensing technique to sense the rotor position.

Key Features

  • Full-wave commutation without position sensors.
  • Built-in start-up circuitry.
  • Six outputs that can drive three external transistor pairs:.
  • output current 0.2 A (typ. ).
  • low saturation voltage.
  • built-in current limiter.
  • Thermal protection.
  • Tacho output without extra sensor.
  • Transconductance amplifier for an external control transistor.
  • Motor brake facility. QUICK.
