Pin Description (continued)
Fault Delay Input. Determines the delay of
the FAULT and FAULT outputs. A capacitor
attached to FLTDLY ensures proper startup
(see the Typical Operating Characteristics) .
FLTDLY = GND: holds FAULT low and
FAULT high. When FLTDLY = GND, EN =
high, EN = low, and V
operational range, the safety circuitry is
inactive.
Low-Voltage Operation. Connect to GND for
4.5V to 5.5V operation. Leave open for 3.0V
to 5.5V operation (Table 2).
Supply Voltage
Noninverting Data Input
Inverting Data Input
Reference Voltage. A resistor connected at
REF to MD determines the laser power when
APC is used with common-cathode lasers.
Polarity Input. POL is used for programming
the laser-pinning polarity (Table 4).
Inverting Polarity Input. POL is used for
programming the laser-pinning polarity
(Table 4).
Monitor Diode Connection. MD is used for
automatic power control.
Laser Bias Current Monitor. Used for
programming laser bias current in VCSEL
applications.
Shutdown Driver Output. Provides a
redundant laser shutdown.
Bias-Controlling Transistor Driver. Connects
to the base of an external PNP or NPN
transistor.
