Using IO to Control battery switch

Using IO to Control battery switchhttps://devzone.nordicsemi.com/f/nordic-q-a/83002/using-io-to-control-battery-switchHi, Here is my hardware. VBAT is 3.6-4.2V, UWB_EN is Pin28.By using nrf_gpio_cfg_output( UWB_EN ) to init this IO. Is there any problem?Because when I using nrf_gpio_pin_clear(DC_EN_PIN), there will be a 4.2v(highest) voltage on pin28.en-USTelligent Community 13Wed, 22 Dec 2021 00:53:54 GMTRE: Using IO to Control battery switchhttps://devzone.nordicsemi.com/thread/344700?ContentTypeID=1Wed, 22 Dec 2021 00:53:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fbac9f53-7036-420d-9d68-5d970baca068Taylor<p>Thanks!</p><div style="clear:both;"></div>RE: Using IO to Control battery switchhttps://devzone.nordicsemi.com/thread/344626?ContentTypeID=1Tue, 21 Dec 2021 14:20:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7770e056-3b68-4ef0-acc0-a10718cb5019Bendik Heiskel<p>The maximum tolerated voltage on the GPIO pins are 3.9V. 4.2V is to high for the GPIO pin and can damage the chip.</p> <p> </p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>
