NOTE:
1. VBATT supply shown above must be connected to the power supply pins of IC/Module. For example, SDIO_IO_VDD, ULP_IO_VDD, UULP_VBATT_1, etc.
3.3.2.4
Power-Up Sequence with EXT_PG_EN used to control supply voltages
The EXT_PG_EN functionality (available on one of the pins) can be used to control supply voltages other than UULP_VBATT supplies (Always-ON VBATT Power supplies). If
EXT_PG_EN functionality is enabled, it will be '1' by default immediately after power-on. The diagram below shows typical connections of EXT_PG_EN and UULP_VBATT
pins. Use one of the application connections shown above in conjunction to the below. The main purpose of th is connection diagram and waveform is to show the
EXT_PG_EN connection and its waveform in relation to the others.
NOTE:
1. Above shown is a typical connection diagram. Some of the supply pins shown above may not be present in the SoC/module. Check the PinOut table in this datasheet and
connect accordingly.
2. * = Provide the supply voltages as per the specifications mentioned in the datasheet.
3. Typical Power circuitry can be a Power Gate (Transistor or IC based), or a Voltage Regulator.
