Tool/software:
Hi,
We have some BQ25758 OCP qeusiton wants to clarify.
Expected Behavior when OCP is triggered
- BQ25758 INT pin active low to indicate an interrupt. -> INT pin is triggered after OCP -> Fail, the source of INT seems not to be OCP, but Charger_stat change.
- Read 0x24 and check if IBAT_OCP_STAT is 1. -> The value read out is 0x00. -> Fail
Questions are as follows
- How to enable OCP function? Do we only need to config 0x02 output_current_limit? Does other register need to config?
- What OCP behavior should we expect after setting the OCP current limit? BQ25758 resets itself or raises an interrupt so the host can handle the OCP condition.
- Which reg bit should we check after OCP triggered?
- When OCP happen, can BQ25758 keep output power and not to reset power?
- How to read current? is it read from 0x2F and 0x30? Should we assert other function?
Thanks!
Jeff
