GENERAL DESCRIPTION
The TDA5147CH is an ASIC combination chip that
includes the following functions:
spindle motor driver
voice coil motor driver
retract
Power-on.
The circuit is contained in a 64-pin QFP package.
The TDA5147CH is controlled by a custom digital ASIC
(see Chapter “Application Information”). 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 pin SIPWM).
Control of the VCM circuits is via the V
IPWMH
and V
IPWML
input signals. These inputs provide control of the voice coil
current.
