Laser Diode Driver with APC Amplifier for Printers
ISL58113
The ISL58113 is a high-performance laser driver that
provides controlled current to grounded laser diodes. A
bias current is summed with the switched current at the
IOUT output, allowing the user to optimize laser diode
performance.
Output switched current flows when the LVDS signal
DATA is high. The output current returns to the
fixed-threshold value when DATA is low. Complete IOUT
shut-off is achieved by holding the CHPEN low, which will
override all other control pins.
A fast settling APC amplifier connects directly to the
monitor diode. The ISL58113 does not exhibit any
time-dependent droop since the calibration gain is stored
as a digital number.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die
attach materials, and 100% matte tin plate plus anneal
(e3 termination finish, which is RoHS compliant and
compatible with both SnPb and Pb-free soldering
operations). Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
