UA8954
UA8954 is 4 CHANNEL BTL DRIVER manufactured by Unisonic Technologies.
UNISONIC TECHNOLOGIES CO., LTD
LINEAR INTEGRATED CIRCUIT
4 CHANNEL BTL DRIVER FOR CD/CD-ROM
- Features
- Wide dynamic range, (4.0V (typ.) at PreVcc=12V, PVcc=5V, RL=8Ω)
- Level shift circuit built in.
- Thermal-shut-down circuit built in.
- UTC UA8954 is a 4 channel driver for optical disc motor driver. Dual channel current feedback type drivers are built in, in addition to dual channel motor drivers.
- Stand-by mode built in.
- Separating Vcc into Pre+Power of sled motor, Power of loading motor and Power of actuator, can make better power efficiency, by low supply voltage drive. <Actuator driver>
Current phase lag influenced load inductance is little, because this type is...
