Hello,
We are using the BQ24250, and we are confused by one section in the data sheet. What is the "short circuit current limit". We just want to clarify that piece.
“When no input source is available at the input and the battery is connected, the battery FET is turned on similar
to supplement mode. The battery must be above VBATUVLO threshold to turn on the SYS output. In this mode,
the current is not regulated; however, there is a short circuit current limit. If the short circuit limit is reached, the
battery FET is turned off for the deglitch time. After the deglitch time, the battery FET is turned on to test and see
if the short has been removed. If it has not, the FET turns off and the process repeats until the short is removed.
This process is to protect the internal FET from over current.”
Thank you
