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

µm 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
