LMH13000: possiblity of change current direction by changing VSET polarity

SELAMI SAHIN

Part Number: LMH13000


Tool/software:

Hello,

Is it possible to change the direction of output current by changing VSET voltage of LMH13000. I mean, could 0 to -2V be applied to VSET voltage to drive the current such as output of the chip and drive through anode of the laser diode?

    Hi Selami,

    The current direction in LMH13000 cannot be changed, it can only sink current into the device.

    What's the current value which you want to source to the Laser and also is that a DC current or pulsed current?

    Regards
