• Control multiple LTC4162-S with one I2C bus and DVCC as enable

    I want to use one I2C bus to control until 4 ic's LTC4162-S. I was thinking in use a I2C hub ic or control the i2c lines of each ltc4162-s with mosfet or analog switch. However, I think I can use the DVCC pin as enable for the communication, this means…

  • LTC4162-S as a standalone charger without powerpath

    I am planning to use the IC as a standalone charger without use the powerpath. So I was wondering if I can remove the powerpath components (infet, batfet, r_sense) in order to make a more simple design and save extra costs. If it is possible, Could you…

  • LTC4162-S battery charge issue


    We are designing a product which has a built in battery and it can also use an external power supply. We are using the LTC4162-S IC, but we have an issue with the battery charging part. We have used this IC in another project and it was working…

  • LTC4162-S not recognizing missing battery

    If we power up our system with battery installed and then remove the battery we cannot seem to detect missing battery.   It appears to remain within the cc_cv_charge state.    The battery voltage continues to measure 6.5 volts.  There is a 10uF cap hanging…

  • LTC4162-S (DEMO DC2038A) Simulated Temperature Adjustment


    I have a LTC4162-S DEMO (DC2038A) board and GUI. In the user manual for the DC2038A, on page 5 under the NTC Thermistor Measurement section it says "When the JP3 is set to EMULATE, the NTC connections are routed to an on-board electronic potentiaometer…

  • LTC4162-S issue

    Dear Sir,

    I have two question about the LTC4162-S as below.

    1. I download the latest the QuikEval and try to connect the DC2038A-H via the Micro USB port, but the USB driver is not found by PC. Could you please tell us how to setup the DC2038A-H with QuikEval…

  • RE: LTC4162-S Battery Reverse Connection

    Could you please explain why connecting a 470k resistor from Vbatt (24v) to RT pin (which is using a 63.4k resistor to ground) will disable the charger?

  • LTC4162-S Design Question


         I would like to ask about the voltage accuracy and current accuracy of the LTC4162-S, and what are the requirements for controlling the mcu of the LTC4162-S? My initial choice is STM8S0003F3U6TR, mainly due to the size and function and cost, and the recommended frequency of my specificat…
