ISL58315CRTZ-T7

Laser Drivers Overview

The ISL58315CRTZ-T7 is a high-speed, triple-output laser diode driver (LDD) designed for laser scanning projector systems requiring three channels modulated at high speed with independent current control. It supports up to 720-pixel HD resolution and delivers up to 1A of peak current output. The device features fast output switching speeds with pulse rise/fall times of 1ns to 2ns for crisp pixels. It includes Intersil patented laser voltage sampler function for dynamic power management and SmartLinearizer™ DAC feature for linear transfer functions. The LDD accepts flexible 10-bit or 15-bit RGB pixel input formats, supporting a maximum data input rate of 300MHz in 10-bit RGB mode. Blanking time power reduction reduces LDD current consumption to 3mA typical.

Laser Drivers Procurement Notes

Verify the complete part number including suffixes such as CRTZ-T7 against official Renesas documentation to ensure correct package type and reel configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the datasheet revision date to ensure compatibility with your system design specifications.

Laser Drivers Selection Notes

Select this component when designing laser scanning projectors requiring independent current control for three laser channels. Consider its support for 10-bit or 15-bit parallel video interfaces based on your speed and power trade-offs. Evaluate the integrated heater function if using SHG green lasers to minimize external component count. Ensure your system can accommodate the single 3.3V supply and 1.8V video interface requirements.
