my customer discover large leakage (1mA) at 3D3V_RTC_AUX Vin of TLV74315 during "coin battery supply",
as you can see below the red circle, when they decrease the resistor value, the leakage disappear,
also when they use adapter input ( another diode's input 3D3V_LPS) , no leakage occur miraculously.
moreover, the other strange thing is when he plugged the adapter then plug out (only battery) , the IC function work again and no issue.
does this has something to do with the RC between battery and vin when power up? (R=1Kohm, C=2uF )
