the anode or cathode of a monitor photodiode or to a
resistor-divider, depending on the specific application
circuit. Three application circuits are supported:
common-cathode laser with photodiode, common-
cathode laser without photodiode, and common-anode
laser with photodiode (as shown in the
Design Procedure
section). The POL and
POL
inputs determine the laser
pinning (common cathode, common anode) (Table 4).
The smooth-start circuitry prevents current spikes to the
laser during power-up or enable; this ensures compliance
with safety requirements and extends the life of the laser.
The power-control amplifier drives an external transistor
to control the laser bias current. In a fault condition, the
power-control amplifier’s output is disabled (high
