Re: MODM7AE70 GPIO Pin States at Boot

wbradley,

Just wanted to post a final update -- I was able to add a heavier pulldown to the enable pins on that power distribution board and that mitigated my issue.

Thanks again,
Jordan

Re: MODM7AE70 GPIO Pin States at Boot


Hi there! The default state for many chips like ours is to be internally pulled high with relatively weak impedance by default. Your circuit should be designed so that it fails-safe when the pins aren't being actively driven, in your case probably with a moderate pull-down resistor. This also ...

MODM7AE70 GPIO Pin States at Boot

Good Afternoon,

I'm using a MODM7AE70 to handle switching on/off components in a system through a custom power distribution board. The regulators and FET's being actuated on that power distribution board are 3.3V logic high. What I'm seeing on boot of the Netburner is that all of the GPIO pins are ...
