Stm32f030f4p6 POR current problem

Hi,

I have designed low power detector with using stm32f030f4p6. In normal state detector is supplied with 24Vdc and it consumes 50uA. But when I supply the detector with 2V, mcu consumes 2mA. This high current consumption is very important, because when energized the alarm panel after connect 30 detectors, detectors input voltage increase slowly and all detectors cause the high current consumption at 2V levels.

When I read the dataheet, detector enters the reset state at 2V. In this state, it consumes 2mA. Is it normal? Or are there any solution to fix this?

 

Sorry for my poor English.

Thanks in advance.
