Hi,
I'm using the BQ40Z50-R1 chip to simulate a battery and I am using the suggested reference design schematic provided. The issue I am seeing is when I apply voltage (16.8v) to the circuit, voltage appears to not go beyond the CHG and DCHG FETs. I am able to establish communication to the chip via Battery Management Studio.
Within Battery Management Studio, If I apply power via the battery cell side, I am able to see values for Cell voltage 1-4, and BAT pin Voltage but not PACK pin voltage
If i apply power via Pack Pin Voltage side, I am able to only read the PACK pin voltage
I'm confused as to what kind of conditions am I observing.
Could it be that the FETs are not enabled or is the fuel gauge stuck in Sleep mode or Shutdown mode?
Thanks,
