BQ24616 and BQ24133 - Datasheet parameters

Other Parts Discussed in Thread: BQ24133, BQ24616

Hi, We are unable to understand what values correspond to the lower and upper thresholds of the overvoltage?

Could you help us out with it?

Regards

    Atul,

    There are more than one overvoltage parameter for these devices.  If you are looking for the input (adapter) over voltage protection thresholds here is the information for both parts:

    bq24133 (Datasheet page 9), when the OVPSET pin is above 1.6 V (typical) the part will recognize overvoltage condition on the input supply. Minimum is 1.55V and Maximum is 1.65V. 

    OVPSET Pin voltage is used to indicate valid input voltage range.  When this pin is > 1.6V overvoltage condition is recognized and <0.5V is under voltage condition.   Use an external resister divider from input to OVPSET to AGND to program this voltage. Figure 1 from the datasheet (page 5) shows a typical application with a 12V input and a 18V OVP. 

      

     

    bq24616 (Datasheet page 7), Input overvoltage condition is triggered when rising voltage on VCC pin crosses 32V (typical), 31.04V (min) and 32.96V (max).

    Please let me know if this answers your questions or if you have any other questions regarding other datasheet specs. 

    Best Regards,

    Rachel
