6.2.5 SPI/I²C/I3C Configuration with VDD, VDDIO ramp-up time <10 μs
Figure 23: SPI/I²C/I3C Configuration with fast VDD, VDDIO ramp-up times
If VDD or VDDIO ramp-up times are not controlled and are faster than 10us, like in a direct connection to battery, the
BMP581 inrush current should be externally limited to avoid damages from repeated power cycles using a 10 Ohm
resistance, as depicted in Figure 28.
