TPS3808-EP /MR pulse width

Other Parts Discussed in Thread: TPS3808-EP, TPS3808

Hello,

I want to know if is it correct the information given in the last datasheet of TPS3808-EP (SBVS103C–APRIL 2008–REVISED NOVEMBER 2008) about input /MR pulse width, "Input pulse width to /RESET". It shows tht this values 0.001 us! With this pulse width, the device is to much sensitive to electric noise.

If the information is correct, how can I limit the noise in this pin?

Thank you

If you need to filter noise off of the TPS3808 /MR ( master reset) input, you can use an RC filter to ensure the TPS3808 only responds to your signal. Without any filtering, the TPS3808 could react to a 0.001us /MR pulse.

There is additional information on the TPS3808 /MR in another post in the forum. This post is found by searching on "TPS3808 /MR"
