I am attempting to create a circuit using a TUSB2036 usb hub IC that automatically starts when it is powered on.
The datasheet states for the inverted RESET pin
RESET is an active low TTL input with hysteresis and must be asserted at power up. When RESET is asserted, all logic is initialized. Generally, a reset with a pulse width between 100μs and 1 ms is recommended after 3.3-V Vcc reaches its 90%.
My understanding is that this means I have to supply a delayed (to allow the power to fully initialise), active low (because the RESET pin is active low), ~1ms pulse that is triggered when the power is connected. Is this correct?
If so, how would I go about doing this? I have tried using a 555 timer but I can't get it to work. I tried looking up monostable 555 timer circuits but they all the ones I found are effectively pulse extenders which is not what I need. I also found this question that also used a 555 timer but I was unable to use the circuit in the answers to generate a pulse that is short enough.
Is using a 555 timer the way to do this or is there a different IC that do this simpler. I don't really have any particular constraints apart from the usual cheaper and simpler.
