Description
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 1 A CW and 3 A
pulsed current, depending on the frequency, duty cycle,
and heat dissipation.
The switches can be paralleled
for up to 3 A CW and 9 A pulsed current.
A 1.4 mm x 1.4 mm 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.
