We have a question concerning the power connections of the TXS0206-29 chip (SD-CARD interfacing); where not sure how to connect the VBatt power pin (B2). The datasheet says on page 3 that VBatt is the ’’LDO input voltage from battery-supply’’. From the datasheet, this Vbatt seems to be the only LDO voltage input. If we don’t use a battery supply, should we connect this pin to another source of power, or the internal LDO would simply be powered from VCCA?
