Other Parts Discussed in Thread: AWR1642BOOST
Hello,
On a custom board we are making now, we are using the PMIC LP87524JRNFTQ1 with the AWR1843 (using LC filters).
The PMIC has a PGOOD signal output configurable via I2C, and we're considering using it as a reset input for the AWR1843 (R3 ball).
I've checked the power up values of the PMIC and it's seems that the PGOOD will be open drain, active high (OD) when all rails are valid. This seems to fit a direct connection to the AWR1843.
Can you please double check this? Can the PGOOD signal be connected directly to the reset input of the AWR1843, assuming I pull up with a 10k resistor to 3.3V rail?
Are there additional concerns of this connection during normal operation (after power up, assuming we stay with the default configurations of the PMIC) ?
BTW, on the AWR1642BOOST I see that there was no monitoring done at all (ignoring the button and XDS), and the reset input was connected using a PU and a 0.1uF cap.
Please advise,
Thank you
Guy
