Title:
CIRCUIT STRUCTURE, DRIVING CIRCUIT OF SEMICONDUCTOR LASER, AND LASER RADAR TRANSMITTING MODULE
Document Type and Number:
WIPO Patent Application WO/2024/082726
Kind Code:
A1
Abstract:
The present application provides a circuit structure, a driving circuit of a semiconductor laser, and a laser radar transmitting module. The circuit structure comprises a charging circuit and a discharging circuit; an input end of the charging circuit is connected to a preset power supply, and an output end of the charging circuit is connected to the discharging circuit; the discharging circuit is further connected to an anode of a semiconductor laser, and a cathode of the semiconductor laser is grounded; the charging circuit is arranged on a first circuit board, and the discharging circuit and the semiconductor laser are arranged on a second circuit board. The present application can satisfy requirements for high-pulse current of semiconductor lasers, and also avoid the problem of insufficient reliability of semiconductor lasers caused by high temperatures.
