摘要： In a driver circuit couplable to laser diodes, a semiconductor body has a first surface. First and second control switches have drains coupled to a drain metallization, which is couplable to a power supply line, and sources coupled to respective first and second source metallizations, which are couplable to cathode terminals of the laser diodes and a reference node. A plurality of high-side switches have drains coupled to the drain metallization and sources coupled to third source metallizations, each of which is coupled to a respective drive output node for driving an anode terminal of a respective laser diode. The drain, first, second and third source metallizations face the first surface of the semiconductor body, which faces the laser diodes. The second and third source metallizations are aligned with one another and are superimposed to the respective source terminals of the second control switch and high-side switches.
