DATASHEET
Programmable High Speed Single Channel Laser Diode
Driver
ISL58214
The ISL58214 is a highly integrated laser diode driver designed
to support a laser beam scanning MEMS projector. Operating
from a single 5V analog supply, it directly drives either a
cathode-grounded laser, or a floating laser whose anode is
connected to a high voltage supply. The ISL58214 is configured
through a serial interface.
An integrated 10-bit high power DAC drives the selected laser.
The desired current level can be scaled by a 10-bit DAC
programmed through a serial interface or the ISLOPE pin to
compensate for ambient brightness, speed variation or laser
sensitivity change.
The CLK pin clocks in the data on the rising edge of CLK. The
LOWP line gates the output off when HIGH.
Features
• Direct drive for floating laser, or cathode grounded. Supports
Red, ‘Green’ or Blue laser
• Up to 1000mA maximum total output (ISRC) with 1.5ns typical
tr/tf
• Up to 500mA maximum total output (ISNK) with 1ns typical
tr/tf.
• 10-bit x 10-bit multiplying DAC output provides 10-bit full scale
adjustment and 10-bit resolution at any full scale output
• ISLOPE input allows compensation for laser slope, ambient
light, and sweep speed variation
• High-speed SPI Serial input works up to 50MHz
• 10-bit video code capable of operating up to 100MHz pixel
data rate
• Integrated programmable HFM (High Frequency Modulation)
for laser stabilization and speckle reduction
• Pb-free (RoHS compliant)
Applications
• RGB laser based projector or pico projector
• Hand held projector
• General purpose laser diode driver
• General purpose high current driver/controller
