A Tel: (408) 260-3400 FAX: (408) 248-3416 GENERAL DESCRIPTION The CMI8804 is a silicon monolithic integrated circuit and is a four channel driver for optical disc motor drivers.
The CMI8804 has a wide dynamic range of 4.
0V(typ.
) at PreVcc=12V, PVcc=5V, and RL=8Ω.
By separating the into pre+power of sled driver, power of a loading driver, and power of an actuator, the CMI8804 has made the power efficiency better by using low supply voltage.
The CMI8804 has integrated and built in to itself a level shift circuit, a thermal-shut-down circuit, and a stand-by mode.
The actuator drive is a current feedback type and the current phase lag influenced load inductance is little.
On the sled motor driver, input pins consist of (+) and (-), which thus provides various input types, such as the differential input.
