BQ40Z50-R2: Compatibility with Battery Management Studio

6044945
Prodigy 40 points
Part Number: BQ40Z50-R2

Hello,

We are using the Battery Management Studio to configure a BQ40Z50-R2.
The goal is to get the BTP INT output working.
But for now the BTP INT output pin is stuck at 0.

When using the Battery Management Studio, we have a confusing reading of BTP_INT.
In the Registers window: BTP_INT=1.
In the Datamemory window: BTP_INT=0.

Is the Battery Management Studio reporting properly BTP_INT?
Is the BTP_INT bit following the BTP_INT pin behavior?
How is its possible to control the BTP_INT pin behavior?

Regards.

    Hi,

    BTP_EN in df is the enable bit for BTP function. There is no BTP_INT. If that is set, then the BTP feature will trigger as expected. If it's unset, the BTP trigger will follow the input based on remcap but it won't pulse or provide an interrupt. Please follow TRM chapter 6 for instructions.
