Other Parts Discussed in Thread: EV2400,
Hi,
I'm evaluating BQ27421EVM-G1A with battery management studio v0.32 and EV2400.
I have configure all the parameters in "Parameter Q&A". In application configuration, I set "gauge will use the bin to detect battery insertion", "Exernal pull-up on the BIN pin", set "BAT_LOW" and "Low" for GPIOPOL and "Int Temp" for gauge temperature.
In data Memory, I set "SOC1 Set Threshold" to 95% and "SOC1 Clear Threshold" to 98% to see the change of SOC1 register faster.
When the battery is discharging from 100% to 90%, I see the SOC1 bit in Flags register changes from 0 to 1. But the GPOUT state don't change. If I charge the battery to 100%, the SOC1 bit return to 0 but the GPOUT state is unchanged.
I tried with Vdd or Vext (3,3V) but the problem is the same...
GPOUT is never low (always arround 1,8/2V)
I use a led to see the status of GPOUT.
If I configure the bit BATLOWEN to 0, I don't see pulse on GPOUT pin.
Why is wrong in my configuration?
Thansk for your help.
