• Connecting ADP5092 with a Wireless Power Receiver

    Hello-We need to integrate Wireless Power Receiver (BQ51051B) in our design for wireless sensor that uses ADP5092 to charge a 3.7v Li-Po battery from solar cells. The battery is connected directly to the BAT pin on ADP5092. I was wondering if we can also…

  • ADP5092 configuration

    Hi EZ, 

    I am currently trying to re-configure the ADP5092. This is the behavior that I am looking for :

    -Vsys = 2.4V constant to power up my microprocessor

    -Reg_out = 3.6V constant to power up another ADP

    According to the datasheet, if I want to fix…

  • RE: What is Hysteresis Boost?

    The boost of ADP5092 is used hysteresis mode to control the output voltage. The output voltage cannot be higher than BAT. When the BAT voltage is lower than REG_OUT, it would be in LDO mode.

  • RE: Best LI Ion Battery and Solar and System Power

    Hi Alan,

    1. The difference between the ADP5091 and ADP5092 is pin 11. ADP5091 pin 11 is "LLD" and ADP5092 pin 11 is "REG_GOOD". Here's a quick description for each:

    2. The best choice mostly depends on your solar panel and battery…

  • ADP5091 / ADP5092 BACK_UP to REG_OUT

    It is a question about ADP5091 / ADP5092.
    Is it possible to output to the REG_OUT terminal by input from the BACK_UP terminal?

    It seems impossible in our experiment on the evaluation board.

    Best regards

  • RE: ADP5091 function

    Hi HOD.

    ADP5092 REG_OUT is same as ADP5091 but therer is no REG_OUT in ADP5090.



  • What is this symbol?

    This snippet is from the ADP5092 manual, in the functional block diagram.  What is the highlighted component?  Is that an inductor printed right on the dye?  If so, how big is it (in terms of at least order of magnitude)

  • RE: Clarifications regarding ADP 5091 eval board usage

    Hi Sagar,

    Regarding the efficiency, you can refer to the user guide 4 and 5. it's better to connect SYS and BAT together.


    You have to…

  • ADP5091/92 BAT Charging Current Adjustment

    Is there a way to adjust the charging current for BAT output on the ADP5091/92?
    The battery we're planning on using in this application should only be charged at 25mA.


  • About the harvester of ADP5091


    1、我注意到datasheet第一页上“The ADP5091/ADP5092 provide efficient conversion of the harvested limited power from a 6 μW to 600 mW range with submicrowatt operation losses. ”5091可以从PV获得的最大功率就是600mW吗,或者更高?
