Product Information

The triple laser switch iC-HV enables the spike-free switching of VCSEL arrays with well-defined currents at frequencies ranging from DC to 200 MHz.

The VCSEL current is determined by the voltages at pins CIx.

Three fast switches are controlled independently via TTL/LVDS inputs.

The VCSEL array can thus simply be turned on and off or switched between different current levels, defined by the voltages at CIx.

Each switch can be operated up to 1A CW and 3A pulsed current, depending on the frequency, duty cycle, and heat dissipation. The switches can be paralleled for up to 3 A CW and 9A pulsed current.

A 1.4mm x 1.4mm pad (pin LDK) allows the VCSEL array to be mounted directly onto the iC-HV, yielding the shortest possible VCSEL-current track-length for maximum switching speed.

The integrated thermal shutdown feature protects the iC-HV from damage by excessive temperature.
