Ordering number: EN*5825 Monolithic Digital IC LB8118M Actuator Driver for Portable CD Players Preliminary Overview The LB8118M is an actuator driver IC designed for portable CD players that operate at 2.4 V (two Ni-Cd batteries) or 3.0 V (two dry cells). Because the four-channel driver control outputs are divided into two groups, this device reduces power dissipation considerably during double-speed play. Package Dimensions unit : mm 3148-QFP44MA [LB8118M] Functions and Features SANYO : QIP44MA . H bridge drivers (output dynamic range maximum is about 2 V) on chip for four channels to drive each CD actuator (the focus the tracking coil, the spindle motor, and the sled motor). .
