15. 1 KOhm resistor is connected when T4 goes off after entering Low power mode Q12 output of the counter allows connection of the 1 K resistor when the current IDD becomes very low Figure 5 shows how the counter and T4 ensure that 150 ms after IDD CNT EN falling edge the shunt resistor R35 is connected between VDD MCU and the power supply in order to reduce the measurement range to 30 uA full scale when VDD 1 8 V Then after another 150 ms for current stabilization R35 is shorted the IDD measurement is stored in C25 and the MCU is woken up After wakeup the MCU can measure the IDD current corresponding to the Low power mode stored in C25 It is recommended to maintain VDD on the STM32L at a value lower than 3 5 V during low power current measurement to avoid extra current consumption on the NRST pin U11 pin 14 The reason for this is that the NRST pin of the STM32L is connected to the ST LINK MCU T_NRST signal U23 pin 18 and as the ST LINK is powered at 3 3 V a leakage current is injected into the STM32L NRST pin when MCU VDD becomes equal to or greater than 3 5 V Doc ID 18141 Rev 2 ky UMO1018 Hardware and layout 2 16 3 Note Note Ibias current measurement procedure In Low power mode the bias current of operational amplifier input U10 pin 4 is not negligible compared to IDD current typical Ibias is 240 nA To obtain a reliable MCU IDD measurement it is possible to subtract the bias current from the IDD
