Preliminary
EMD2161
100mA LASER Diode Driver
General Description
The EMD2161 is a LASER Diode (LD) driver with up to 100mA 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 100mA driving capability With selectable current limit With Under Voltage Protection
