Current consumption issue in extended sleep mode
Hi!
We developed custom board with DA14586 and current consumption in extended sleep mode is crucial for us. According to datasheet "Current consumption - Typical buck-application in
extended-sleep mode with 64 kB RAM retained, running from XTAL32K oscillator - 2.25 μA". But real current consumption is different from board to board - 2.5uA to 4.5uA(supply voltage is 3V, temperature is about 25°C). I found that supply current also depends on temperature. In colder conditions, current consumption is lower and close to 2.25 μA. In hotter conditions, it can be higher than 8uA.
