GENERAL DESCRIPTION
The TDA5149G is a combination of a voice coil motor
driver and a spindle motor pre-driver, capable of operating
12 V high-performance hard disk drives.
The device integrates a spindle pre-driver that drives three
external N-channel power MOSFETs in order to drive a
three-phase brushless, sensorless DC motor in full wave
mode. In the normal mode, commutations are generated
from the internal Back EMF (BEMF) sensing circuitry.
Commutations, however, can also be generated from an
external source, thereby providing the possibility of driving
the motor in the stepper-motor mode.
The VCM driver is a linear transconductance amplifier
capable of handling currents up to 1.65 A. It allows
external adjustment of the gain and compensation.
The TDA5149G also contains two drivers for a latch that
secures the heads in the event of power-down.
To control functions such as park, brake, sleep or disable
and to program the different timing parameters, the
TDA5149G is provided with a three-wire serial port. A high
precision voltage monitor is also included, for both
5 and 12 V power supplies. Finally, the IC contains a
temperature monitor circuit and an uncommitted
operational amplifier connected to V
DD
, which can be used
freely within the application. The device is contained in a
LQFP64 package with 4 pins connected to the lead frame
for improved heat dissipation.
