Hello,
Regarding to TXS4558, my customer is asking some question.
(Question)
(1)For power up, is power sequence is needed?
Or don’t we need to care power procedure ? (VCC and VBATT)
(2)VBATT is always input to power source but VCC is repeated power on/off
or VCC is unstable as 2.95V⇔1.8V. (It’s changed voltage between 1.8V and 2.95V.)
In this case, is there any impact to TXS4558?
Regards,
