Preliminary
EMD2160
300mA LASER Diode Driver
General Description
The EMD2160 is a LASER Diode (LD) driver
with up to 300mA driving capability and
10kHz pulsed operation. To prevent driving
LD with improper large current, a current
limit circuit is designed in. Once the
protecting circuit is triggered 3 times, the
main driver would be ceased and wake-up
it again by re-power on.
Feature
„ Up to 300mA driving capability
„ With selectable current limit
„ With Under Voltage Protection
The CL100 is designed for selecting current
limit levels. When CL100=Low, the current
limit level is set around 300mA. When
CL100=VCC or Floating, the current limit is
set around 100mA.
