ST25R3918: Excess current in Power-Down mode with I2C_EN HIGH (I²C mode); resolved by switching to SPI
Hi ST team,We’re using the ST25R3918 in a low-power BLE+NFC product. During testing, we noticed unexpected ~10 µA additional current draw when the chip was in Power-Down mode (with all VDD rails active), despite expecting ~1–2 µA per the datasheet.Af...
