hi,
For the circuit below,
Please help check with TI to see our application circuit is fine to use. We will shutdown the LDO_1V8 and only left 3.3V powered to TXB0304 without enable the OE of TXB0304 when in sleep mode, do you see an issue? Supply from primary battery and B1 to B4 are SPI signals.
During our test, we noticed TXB0304 still functional but only 3.3V port got high leakage current. Any suggestion?
Best Regards,
Felix
