• RE: LT3651 overheating

    Hello, this wording is difficult to understand, but some heating is expected with this part since the switching FETs are integrated.

  • LT3650-8.2

    NTC function is described in the datasheet as follows.

    would you teach how LTC3650 detect NTC pin unconnected. what is the threshold voltage to detect unconnected during sourcing 50uA?

    How large additional resistor can I add to NTC pin to increase the…

  • LTM8061EV-8.2 2 Cell Charging


        I am currently designing the circuitry to power my rover. I want to use the LTM8061EV-8.2 to charge two 18650 li-ion batteries in series. Upon researching li-ion batteries, I learned of balance charging. The datasheet does not mention anything…

  • lt3650-8.2 battery removal indication


           If TIMER based charge termination is used, what is the indication for battery removal ? that means charging status LED will turn off or it exhibits blinking pattern, if battery is removed for TIMER based charge termination.

    Thanks & Regards,…

  • LT3650-8.2 doesn NOT terminate the charging

    I tested 8 samples and I found two of 8 does NOT terminate the charging even if VBAT reached 8.23V and the charge current decrease down to 50mA.

    I attach my schematic , please advice me how to fix this problem.

  • ADuCM350 SDK not working on IAR 8.2


    I've been trying to make the ADuCM350 and the debugger work with the latest IAR IDE. However, I've been unsuccessful in this task.

    I did a clean installation: uninstalled my previous IAR IDE, uninstalled the J-link drivers, uninstalled the…

  • RE: How can I increase current range to 4A in CN0352 application


    I am still searching for another option to use instead of ADP5065. As I told earlier, we are testing Li-ion batteries  with rating 0-5V, 4A. Actually LT3651-4.1 or  LT3651-4.2 are matching with the current requirement. But how can I observe various…

  • RE: RE: EVAL-CN0429-EBZ not displaying correct values.

    This is the setup that I have using the CN-0429 gas sensor board, ADuCM355 Arduino Interposer board and the EVAL-ADICUP3029.

    The board that is seen in position 2 will not initialize as seen with the other two boards in position 1 and 4. My guess it that…
