Tool/software:
Dear
Regarding the BQ76952, we currently control the charge and discharge tubes with DCHG and DDSG respectively. Now, we need to utilize the us and ms level overcurrent protection of the BQ76952, so we are considering using SCD and OCD1. We have the following three questions to confirm:
1) As described in the manual, it seems that OCD1 can only be restored by charging. Is that correct? But SCD appears to be able to recover automatically after waiting for a certain period of time. What considerations led BQ76952 to make this distinction?
2) If OCD1 can only be restored by charging, before protection recovery, we are concerned that if there is a large charging current, the internal diode of the discharge tube may not be able to withstand it. We see that Protections:Recovery:Time can be set to 0. In this case, once there is a charging current, how soon can DDSSG recover at the fastest? Also, Protections:Recovery:Time seems to be applied to multiple protections. If we set it to 0 like this, will there be any other impacts?
3) Additionally, I would like to inquire if there is any method by which the main controller can directly remove the protection status of OCD1, in order to achieve the effect of automatically restoring OCD1.
