The entire device can be powered down by presenting the appropriate voltage to the externally available ENABLE pin.
The nRF9160 provides a feature to be able disable power throughout the entire device externally. This can be useful when the device is operating as slave processor where it does not need to be powered on at all times, then it is possible to avoid unnecesary current leaking by driving the ENABLE pin to low. The nRF9160 will not start if is not enabled. Moreover, a change from disable to enable, will result in a power-on-reset behavior inside the device.
Pin Value | Power status | description |
