OPA357: OPA357

Part Number: OPA357
Other Parts Discussed in Thread: LMH13000

Tool/software:

I am trying to design a LED current controlled pulsed circuit (the pulse duration  is 4.6us and the current need to be limited to 5A during the pulse duration 

Does Ti have any mosfet driver solution with current limiter in a single package which uses some high speed op-amps and sense the current and drive the gate to limit the current on  the DS path

    Hello Agxin,

      We have newly released the LMH13000 which is an integrated voltage-controlled current driver for laser diodes that can support continuous current of 50mA to 1A and pulsed current of 50mA to 5A. This will have the output FET integrated within the device. Will this work for your application, or still would prefer a discrete solution.

    Thank you,
    Sima
