8.4.2 Power-up
For the power-up, only the power supplies uV_BAT and uV_CC are significant. As soon as at least one power supply
is above its reset threshold the internal supply uV_IN is available and the Central State Machine gets powered up.
The device TLE9221SX enters into BD_Standby mode within the time period dBD_PowerUp as soon as the voltage
values of the power supplies uV_BAT and uV_CC are above their undervoltage detection threshold limits uBDUVV_BAT
and uBDUVV_CC (see Figure 30).
