12 V Voice Coil Motor Vcm Driver And Spindle Motor Drive Combination Chip

The TDA5147K is an ASIC combination chip that includes the following functions; spindle motor drive, voice coil motor drive, retract, and power-on. The circuit is contained in a 52-pin PLCC package. The TDA5147K (see Fig.1) is controlled by a custom digital ASIC The custom ASIC provides the necessary commutation sequences for the spindle drivers via the SCNTL1, SCNTL2 and SCNTL3 inputs. Spindle speed is monitored by Comparator outputs SENU, SENV and SENWIS. Motor speed control is accomplished by a PWM signal (input at the SIPWM pin). Control of the VCM circuits is via the VIPWMH and VIPWML input signals. These two inputs provide control of the coil current. The VISENSE2 output signal CAN be used to monitor the voice coil current.
