AC Electrical Characteristics–Power Management
Power Switch (VBAT/V33 -> VDD_RTC)
Integrated power switch detects the VDD_RTC SW to coin battery (VBAT) or main power supply (V33).
When there is no V33 (V33=0), the SW will connect the VDD_RTC to VBAT; when V33 goes higher than 2.5V, the VDD_RTC
will be switched to V33 with no delay. After V33 goes lower than 2.3V, the VDD_RTC will be switched to VBAT, no delay.
When VDD_RTC = VBAT, the power SW circuit consumes < 100nA.
When VDD_RTC = V33, the power consumption on VBAT needs to be “0”.
