[1] Typical values assuming 100 Hz < f < 1000 Hz.
[2] Typical values assuming X7R type ceramic capacitor.
[3] Smaller external components can be used in the 500 mA configuration; the AUTOLXA2 and AUTOLXB1 pins must remain
unconnected in this configuration (see Section 8.9.6.3).
[4] Current limited; output limited to 175 % of the max current (or 350 mA); module is switched off after a programmable debounce time
when current exceeds specified limit; afterwards, the On/Off Controller will regularly try to power up the module again (see
Section 8.11.6.2).
[5] Output available at the DOWN2FB pin.

[1] If the system voltage drops below Vth(sysmin), an emergency shutdown is initiated and the system transitions to the Save state.
[2] If the system voltage drops below Vth(syspres), and no backup battery is present (bubpres = 0; see Table 14), the system will be reset and
enter the NoPower state. If a backup battery is connected (VBUBAT > Vth(BUBPRES), the PCF50633 will continue in Save mode, powered
by the backup battery.
[3] If the system voltage is below Vth(syspres), the system will continue to operate in the Save state as long as bubpres = 1 (VBUBAT >
Vth(BUBPRES; see Table 14). If bubpres is reset to 0, the system will be reset and will enter the NoPower state.
[4] Note that VVISA and VREFC are internal signals. Pins VISA and REFC are provided to allow external decoupling capacitors to be
connected. Decoupling is necessary to ensure stable operation.
