Refer to the Table 1 Address Map. The A3 - A0 pins have an internal pull-up.
Refer to the Table 1 Address Map. The A3 - A0 pins have an internal pull-up.
Refer to the Table 1 Address Map. The A3 - A0 pins have an internal pull-up.
Diagnostic output, A 0V - 5V analog signal output limits internally to a range of -0.3V to 5.3V. The output is
the channel addressed by A0 - A3.
No connection.
External resistor to ground with a resistor value equal to the value of the thermo-resistor at the desired laser
temperature. (Typically in the 5k to 10k range)
Laser out of temperature range indication.
Thermo-Resistor output to ground connection for TEC control.
Thermo-Electric Cooler Power FET gate drive.
Feedback to stabilize the TEC loop.
Feedback to stabilize the TEC loop.
Laser over-current indicator flag.
Input control turns shunt Power FET gate drive ON/OFF with 5V CMOS logic. Low turns the shunt Power
FET OFF and the Laser ON. These pins have an internal pull-up.

0.1 F).
Thermal compensation short time constant where T
0.02 F).
Times 10 constant current monitor amplifier input from the low side of the sense resistor.
Times 10 constant current monitor amplifier input from the high side of the sense resistor.
Gate drive to the current source Power FET.
Digital Ground.
Analog Ground.
Filter capacitor for internally generated shunt Power FET gate lower drive voltage level (1 F).
Drive output to shunt Power FET gate.
Filter capacitor for internally generated shunt gate upper voltage level (1 F).
Filter capacitor bypass for internally generated 9V power source (1 F).
Relay output drive from an N-channel FET controls an external relay to switch the Laser power supply or
power supply interlock ON/OFF for both Laser Drivers.
Relay input control with 5V CMOS logic. A high switches on the relay. This pin has an internal pulldown.
Laser power supply ESD protection.
