Figure 6-3. Powergood Window Comparator with Push-Pull Output
6.3.4
3.3-V LDO and 3V3SW Load Switch
The LDO3V powers up when Vin_LDO3V pin goes above the UVLO3V threshold. The LDO3V powers the
internal digital blocks and analog blocks of the PMIC. It is also used as the positive rail of the powergood
comparator and level-shifter outputs. The 3V3 load switch is optional to connect or disconnect the
VOUT3V3SW output to a load. The load switch is enabled by the EN3V3SW pin.
