DUAL CW LASER DIODE DRIVER
LASER DIODE/LED TYPES AND OPERATION MODES
preliminary
Rev B1, Page 11/45
For APC operation a monitor diode is required. This
operation is possible in microcontroller unit (MCU)
mode and in the iC-WK mode.
In automatic current control (ACC) operation there is
no monitor diode and any diode can be operated in
microcontroller unit (MCU) mode.
iC-HT can operate in APC two types of laser
diodes/LEDs with monitor diodes:
• N-Type laser diodes
• M-Type laser diodes
All operations are possible with laser diodes (LDs) or
light emitting diodes (LEDs). In the following text we do
not differ between laser diodes (LDs) and light emitting
diodes (LEDs).
