LA6505 Overview
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.
LA6505 Key Features
- Three-phase brushless motor driver
- Adopts a current feedback direct PWM drive design
- Supports analog inputs and features a V-type control amplifier
- Built-in oscillator circuit (The oscillator frequency can be set with an external capacitor.)
- Soft-switching drive
- FG output for one phase (the U phase)
- Built-in reverse rotation prevention circuit
- Built-in Hall sensor power supply (npn transistor, open collector output)
- Current limiter setting function (The limit is set by the resistor RF.)
- Standby mode (SS) function that operates for the spindle driver and BTL amplifiers. (2) Sled motor driver block
