SL2001A-WHS

Overview

The SL2001A-WHS is a specialized laser diode driver designed for Time-of-Flight (ToF) and LiDAR applications requiring extremely narrow pulses. It features an integrated GaN/MOS drive and a resonant-mode architecture capable of generating laser pulses with a Full Width at Half Maximum (FWHM) of less than 2 nanoseconds. This high-efficiency driver minimizes system no-load power consumption to under 5 mW while providing flexible timing control via I2C.

Why Choose This Part

The driver's resonant-mode architecture provides superior charging efficiency and allows for ultra-fast laser triggering with minimal external components. It includes 7 MTP bytes and 218 OTP bytes for custom timing and fault settings, and its 1mm x 3.5mm WLCSP package is ideal for space-constrained optical assemblies.

Applications

Getting Started

Configuration is handled via the I2C interface to program the MTP memory for fault thresholds and timing settings. Engineers should focus on low-inductance PCB layout around the WLCSP pins to maintain the sub-2ns switching performance, utilizing the dual drive outputs to balance the laser load.
