Normal condition for circuit operation
Fault state* occurs
Does not affect laser power
If POL is a TTL HIGH, a fault state* occurs; other-
wise, the circuit is in normal operation
If POL is a TTL HIGH, a fault state* occurs; other-
wise, the circuit is in normal operation
In common cathode without photodiode configura-
tion, a fault state* occurs; otherwise, does not affect
laser power
Does not affect laser power. If optional FET is used,
the laser output is shut off.
Any fault that occurs cannot be reset. Does not
affect laser power.
Does not affect laser power
Fault state* occurs
Fault state* occurs
In common-cathode configurations, the laser bias
current is shut off. In common anode, high laser
power triggers a fault state.* Shutdown occurs if a
shutdown FET (M1) is used. If shutdown FET is not
used, other means must be used to prevent high
laser power.
