UA8954

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 current feedback. 

<Sled motor driver> 

Input pins consist of (+) and (-), therefore various input types are 

available such as differential input.

<Loading driver> 

 This is a single input Iinear BTL driver.
