Hello,
I have a question about the power consumption stabilisation of the nPM2100.
We configured the nPM2100 with the pins directly to obtain a V_OUT of 3V with a 2477 battery. We varied the voltage from 3.2V to 1V and everything worked fine.
When we switch our device to OFF mode, the consumption is ~5uA (V_BAT = 3V). This is a good result, except that it takes ~3 minutes to achieve this result (I will send the PPK2 measure). We would therefore need to achieve this result in 10 seconds in order to validate the power consumption of this product for the production process.
When the battery is new, the output voltage can be bigger than 3.2V. I think using the auto mode is the better option (HP/LP/ULP/PT).
Initially, we do not have access to the i2c pins to configure the device differently. Could this have been corrected using the BOOST.GPIO, BOOST.PIN or BOOST.OPER registers?
We also have a V_INT capacity of 10uF (the same installed in the evaluation kit). I have read that a value of 10 uF to 22 uF is recommended for a lithium battery.
OFF START (After 0 sec / 12.01uA) OK
OFF MIDDLE (After 10 sec / 108.93uA) NOT OK
OFF END (3 minutes / 5.68uA) OK
How can these good results be achieved in a shorter time?
What are the steps involved?
Thank you for your help.
