Power On Reset of TS334

[YFANG.2]

Hello

I would like to confirm with you the power on reset behavior of TS334.

When I power up the comparator, I see a high level impulse during power on.

I guess there is a power on reset behavior of TS334. In the following figure, the blue curve is the supply voltage, the yellow curve is the output of comparator.

I guess the POR time of TS334 is roughly 50us. Could you confirm this?

Hello YFANG.2,

There is no Power On Reset feature on TS334. In you case, Output is high state during the startup of the comparator, but it also could be different. So don't expect POR and a known output state of the TS334 during startup.
