Hello ST/Forum,
I have a design where there seems to be confusion surrounding the inductor values and names:
In the "PCB design guidelines" the inductors are name L14, L13 and L6.
However, in the codebase, the inductors are called "RM1" and "PMU" inductors.
I cannot find any documentation about the correlation between them
Please clarify what the relation between them is.
1) What inductor does RM1_DIG_ENG_REG map to ?
2) What inductor does PMU_ANA_ENG_REG map to ?
3) Does the chip use the inductor values in RADIO_CONFIG for anything else than BOR detection? Please clarify this.
Please clarify this, as we are having strange shutdowns which are likely caused by this.
info: We are running on:
BlueNRG-2 234 CSP34 with the following setup:
L13 = 10uH
L6 = 15nH
L14 = 4,7nH
We are running with integrated balun, DC-DC converter ON, as described on page 4 in the "PCB design guidelines", AN4819-REV2.
Thanks,
/pedro
