DESCRIPTION
Six channel laser switch iC-HGP enables the
spike-free switching of laser diodes with well-defined
current pulses at frequencies ranging from DC to
200 MHz. The high-side circuit architecture of the
iC-HGP allows the operation of common-cathode
laser diode arrays with cathode grounded.
selected with 30% VDD and LVDS slow switch mode
with 70% VDD at input ELVDS.
The laser diode can thus be turned on and off or
switched between different current levels (LDAx con-
nected) defined by the voltages at CIx.
The diode current is determined by the voltages at
pins CIx.
The six fast switches are controlled independently via
TTL inputs. Input LVDS = hi selects LVDS type inputs
and three channel mode. TTL slow switch mode is
Each channel can be operated up to 500 mA CW and
1500 mA pulsed current depending on the frequency,
duty cycle and heat dissipation.
The integrated thermal shutdown feature protects the
iC-HGP from damage by excessive temperature.
