iC-HGP

3 A HIGH-SIDE LASER SWITCH

Rev A1, Page 2/20

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.

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

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.

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.
