description

ISL58303, ISL58304 is a high-speed three-way output laser diode driver that supports a laser light source Pico projection module with a continuous color gamut. The output channels feature independent programmable bias current and threshold adjustment, supporting a wide range of laser diode manufacturers. These two laser diode drivers offer excellent power efficiency and high system integration, enabling compact and cost-effective system designs.

The system is via a high-speed serial bus and is interfaced by SEN, SCLK and SDIO. The initialization of the internal registers is reset after power-up, the installer runs, and the laser intensity data for each output channel is communicated through this bus.

To assist in reducing laser speckle, this laser diode driver has high frequency modulation that feeds into the modulated laser pulses.

For laser operation safety, the hardware enables the signal (CE) to be matched by an internal register bit. Both are set to enable the device. This prevents unintended malfunctions that can cause unnecessary laser output.
