SUITABLE FOR 5V AND 12V APPLICATION
ONLY ONE HALL SENSOR IS REQUIRED
DESCRIPTION
The L7203 SPINDLE MOTOR IC includes a three
phase brushless spindle motor controller and the
power stage in switching mode. The device is de-
signed for both 5V and 12V OPTICAL DRIVE ap-
plication requiring up to 1.8A peak of current.
The device is realized in BCD5, a 0.7
μ
m Mixed
technology.
The spindle motor position detection is carried
out by means of a single comparator with hyster-
esis. In the start-up phase the "inductive sense
start up method" is used to detect the rotor posi-
tion, determining the direction of starting rotation.
This procedure is implemented by a logic circuit
on chip.
The device applies three sinusoidal voltages to
the motor coils.
This is obtained through the application of the
