https://devzone.nordicsemi.com/f/nordic-q-a/90746/gpio-open-drain-configurationHi Team, I am using nRF52810 gpio to power gate (gpio connected to VIN) ADXL362 . But the ADXL362 recommends a switch(SHUTDOWN) as shown below to discharge the capacitors on the VDD line before powering on. But we missed adding the mosfet and haveen-USTelligent Community 13Fri, 05 Aug 2022 16:27:40 GMThttps://devzone.nordicsemi.com/thread/380440?ContentTypeID=1Fri, 05 Aug 2022 16:27:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fc6ca461-69f2-4111-a30d-4eb1b19a067bhmolesworth<p>Don&#39;t need a MOSFET or R1, the nRF52 already has one. Just make the GPIO pin providing VIN configured (CNF) as a high-drive H0H1 (not open-drain) and the pin will discharge the capacitor when it is set&nbsp;low. There will be a finite time while the capacitor charges (turning VIN on) and later discharges (turning VIN off) so a small delay will be needed to ensure the VIN pin is fully charged or discharged, maybe few hundred uSecs depending on C5 and C10. Internal MOFET R equivalent is (say) 100 Ohm.</p><div style="clear:both;"></div>
