Hi guys,
I am new to electronic design and have been building a few
small devices. I am currently studying the TUSB2046B 4-port
hub controller.
One of the pins is the RESET pin and from what I have read,
this pin needs to be held high, as soon as power is asserted,
for 100uS to 1ms, then held low, maybe using a Schmitt Trigger.
However, I haven't been able to find any documentation on how
one would go about making this POR circuit.
Would someone here please point me to a schematic or circuit
diagram of a POR circuit that would be used for the TUSB2046B?
Is there a chip or device, maybe a TO-92 case device that already
exists to do this?
Anyway, any help would be appreciated.
Thank you,
Ben
