UA9849 - 3-PHASE MOTOR DRIVER

Description

The UTC UA9849 is ICs developed for CD-ROM spindle motor drives.

These ICs possess a short brake and reverserotation brake for two types of brake functions, and also contain FG output and rotation direction detection (FR) circuits, making them high-functionality and high-performance ICs.

Features

  • S.
  • Three-phase, full-wave, pseudo-linear drive system.
  • Built-in power save and thermal shutdown functions.
  • Built-in current limiter and Hall bias circuits.
  • Built-in FG output.
  • Built-in rotation direction detector.
  • Built-in reverse rotation prevention circuit.
  • Built-in short brake pin.
