It delays and slowly ramps the current for maximum protection. Supply up to 2.2 A of current to your laser diode from a single supply (+3.3 V to +6 V). The\u00a0WLD3343HB\u00a0is compatible with Lithium-Ion batteries. For higher compliance voltage, the\u00a0<a title=\"WLD3343\" href=\"http:\/\/www.teamwavelength.com\/maintenance\/product\/wld3343-2-2-a-laser-diode-driver\/\" target=\"_blank\" rel=\"noopener noreferrer\">WLD3343<\/a>\u00a0operates from +5 V to +12 V.<\/p>\n<p>An internal thermostat shuts down the WLD safely if the device temperature exceeds 105\u00b0C. Remotely enable or disable current. Zero leakage current makes it perfect for VCSELs.
