Hello,
I'm using TPS2492EVM-003 and I was measuring nPG delay in case of disabling the output through UVEN.
The datasheets was not very straightforward in this regard, it only explainis a deglitch delay of 9ms in case of over current. I could measure it also exhibits the deglitch delay in case of undervoltage.
My question:
How can the following observation be explained?:
- with a load (regardles if it's 10A, 1A or 1mA), nPG deasserting is delayed with about 9 to 10ms -> this is ok.
- without a load (i.e. a load on VOUT of TPS2492EVM-003), the delay for nPG deasserting is 40ms to 50ms (it is variable). Why is this?
Kind regards.
