PMIC

Hi,

Based on arduino MRK (multiple devices.. 1300, 1310, 1400 gsm) what is the values for the next list based on lipo battery (PMIC - BQ24195 chip) ?

  • setInputCurrentLimit ?
  • setInputVoltageLimit ?
  • setMinimumSystemVoltage ?
  • setChargeCurrent ?
  • setPreChargeCurrent ?
  • setTermChargeCurrent ?
  • setChargeVoltage ?

Are you asking what default value should you use for the MKR to work correctly?

have you tried taking a factory set device and call

  • getInputCurrentLimit
  • getInputVoltageLimit
  • getMinimumSystemVoltage
  • getChargeCurrent
  • getPreChargeCurrent
  • getTermChargeCurrent
  • getChargeVoltage

to see what the default values are?

(that library is buggy and not stable.)

HAHA nice idea :slight_smile:

DEFAULT VALUES:

19:11:57.004 -> getInputCurrentLimit: 3.00
19:11:57.004 -> getInputVoltageLimit: 3.88
19:11:57.004 -> getMinimumSystemVoltage: 3.50
19:11:57.004 -> getChargeCurrent: 0.51
19:11:57.004 -> getPreChargeCurrent: 0.26
19:11:57.004 -> getTermChargeCurrent: 0.26
19:11:57.004 -> getChargeVoltage: 4.11

but , I'm using a 5V 1A inductive charger connected to VIN pin..

What is the best configuration ?
I can change Input Voltage Limit to 5V ?
Current Limit to 2A ?
Minimum System Voltage to 3.3 V?
ChargeCurrent to 1A ?
getChargeVoltage to 5V ?

The problem is, my arduino MKR GSM 1400, connected via USB charge with max current of 0.048mA .. why?

I don’t know enough about the board design to comment, you might find good info in that thread
