LA6505 - 6-Channel Driver

Key Features

  • a soft switching function that minimizes spindle motor drive noise by making the current changes at each phase switch more gradual. The sled motor driver implements two-phase stepping drive and supports direct PWM inputs. The LA6505 uses a BTL amplifier design for the focus and tracking driver blocks, and a similar design for the loading driver as well. Functions (1) Spindle motor driver block.
  • Three-phase brushless motor driver.
  • Adopts a current feedback direct PWM drive desi.

Ordering number : ENA0595 Monolithic Linear IC LA6505 Overview For CD-ROM, DVD-ROM and MD players Six-Channel Driver The LA6505 is a six-channel driver for CD and MD players and recorders. It adopts direct PWM drive output in the spindle motor drive to minimize heat generation at high spindle speeds. It also features a soft switching function that minimizes spindle motor drive noise by making the current changes at each phase switch more gradual. The sled motor driver implements two-phase stepping drive and supports direct PWM inputs. The LA6505 uses a BTL amplifier design for the focus and tracking driver blocks, and a similar design for the loading driver as well.
