BQ24090: Which condition BQ24090 will go SHORT PROTECTION status

Part Number: BQ24090


If BQ24090 will go under SHORT PROTECTION status, when Vout down to 0.8v? Because i connect BQ24090 to Boost IC start working voltage lower than 0.8v, and find BQ24090 stop working.

And what means of Recovery ≥ VOUT(SC) + VOUT(SC-HYS) ?


  • Hi Leo,

    When the BQ24090 detects that the OUT pin is 0.8V and lower, the current is limited to 15mA. What is the input current into the boost converter? 

    The parameter you highlighted is the hysteresis which is the threshold where once OUT short is detected, it will need the VOUT to above VOUT(SC-HYS) to detect that it is not in OUT short mode.
