Other Parts Discussed in Thread: BQSTUDIO
Hello,
I was testing the fault conditions on the BQ27742-G1, in particular the firmware ones given from calling "SafetyStatus(): 0x1A and 0x1B" (See Section 4.14.1 of the Technical Reference Manual)
The UVP, OVP fired as expected when I hooked up a battery simulator and brought it past the thresholds. However when raising the temperature with a heat gun to test for the OTC (or OTD) conditions, the TDD (Tab Disconnect) occurs first sometime around increasing past 100 degC (I converted the 0.1K to C) and then since it shuts down, I can never reach a OTC or OTD condition. I'm printing the temperature to a serial monitor and verifying it does increase as expected.
Based on what I can read in the manual, I'm not seeing why TDD would occur in this scenario and why OTC would not. Can someone explain why this is occurring and how I can better test for OTC and OTD?
Best regards,
Christopher
