On our boards with mounted PVF60GS151CMK40 Rev C2 and PVF61NN151CMK50 1N02G the VBAT pin consumes 1-2mA instead the 45uA from datasheet, if the main power is switched off. Also on our Tower board with CPU Test Rev A5 the current is ~90uA. Is there any issue?Does anyone else have this problem?
Needs any CPU internal block connected on VBAT a configuration to reduce this current (e.g. SRTC)?
We already set SOSC_EN to 1 on first start and OSC32K is working. Also RTC is running.
We dont measure any voltage on Tamper pins. Any idea to fix this?
