Laser Diode Driver Pin Descriptions (see drawing below) | ||
Pin | Name | Description |
1 | Aux V+ | For Type C laser diodes only. |
2 | PD Aux | For Type C laser diodes only. |
3 | LD Enable | Enable Output Current = +3 to +5 V |
Disable Output Current = Ground or Floating | ||
4 | LIM I Stat | LIMIT Status. LIMIT = Ground Normal Operation = High Impedance |
If Limit is detected, laser diode current will turn off, Limit I LED will Light. | ||
Toggle LD Enable to restart laser diode current. | ||
5 | LIM I Monitor | Current Limit setpoint monitor. Impedance = 1000 Ohms Output 0 to 2.5V |
Note: Current limit needs to be set 0.2V above desired limit level. | ||
6 | Common | Measurement ground. Low current return used only with pins 5, 7, 8, and 9. |
Shorted to pin 11 internally. | ||
7 | I Monitor | Laser Diode current monitor. Impedance is 1000 Ohms Output 0 to 2.5V |
8 | P Monitor | Power monitor (PD current monitor). Impedance is 1000 Ohms Output 0 to 2.5V |
9 | Analog Input | Remote setpoint or modulation input. Input impedance = 1 mega Ohm Input 0 to 5V |
Connect Pin 9 to Pin 6 when not in use. | ||
10 | +5V | Supply voltage to control electronics. Min +4.5V Max +5.5V |
11 | GND | Power supply ground. Used with pin 10 for high current return. |
12 | LD Anode/+LD Supply | Laser Diode Anode and laser diode supply connection. |
Recommended +LD Supply for single laser is +5V. Maximum +30V | ||
Caution: Too high a voltage may thermally damage the Laser Diode Driver. | ||
13 | LD Cathode | Laser Diode Cathode |
14 | PD Anode | For Type A or B laser diodes, Photodiode Anode. |
15 | PD Cathode | Photodiode Cathode |
