Hello folks!
I am using the next schematic to drive a fiber optic tx:
Note that Vcc= 5V/3A
I am wondering because the driver SN55452BJG is broken very often due to the high current. I would like to find a solution in order to limit the current only in the collector of the driver trt, because I need that such high current on the fiber optic side in order to achieve an enough luminosity power....
On the other hand after reading the datasheet od the FO Tx HFBR-1412Z, I could see that they use a diode on the collector og the trt (see test circuit). This diode could be used as a safety protection of the driver? See next pic:
Any idea?
Thanks.
