    Hello
    I am trying to find a good solution for this design.
    I have to design a fiber optic switch driver.
    The load takes ±2.5V during 1ms and sinks 250mA.

    I have thought of a H-bridge integrated driver but it seems quite
    complicated to have that kind of device operating at 2.5V. All I
    need, is a device that the uController will supply a 1ms pulse to, and
    during this time, +2.5V or -2.5V will be apply to the pins of the
    switch to make it latch. It would of course be simpler if it was
    ±5V...

    What would you guys suggest ?
