Hi,We are using the ST3115 on our product and we are facing sometimes some strange behaviors on gauge reported SOC vs OCV values according to the current flowing in/out the battery. Until now we are using the ST3115 always in mixed mode.It's told in ...
Hi Community, I work on L9788 IC ( with SPC57). And I try to write Driver of L9788. Does ST have L9788 IC Driver? And Can you share with me?
Hello, I am on the RX FOD Tunning (BPP) phase, and I have a question. In the document, it is written - Reading Ptx and Prx is done automatically when using STEVAL- WBC86TX . But I am using just custom board, so I recorded the power from the "Chart...
Posted on June 06, 2018 at 16:57I'm doing a pcb design using the STBC03 for managing the battery (power path and battery charger). It has a 0.4mm pitch BGA30 footprint. Has anybody done a design like this? Is there any guideline for it? Thanks.#bga-...
1. Fault signal trigger: Communication error, what is the mechanism of its occurrence2. Does a watchdog timeout lower the Fault signal?3. Direct control mode, does the watchdog work?4. What is the tWD value?
HiI am looking some guidance how to use the PG pin to indicate the power good mode with fixed versions of LD39100. (3.3 and 1.8V versions.) I plan to use the 3.3V output as an input for the fixed 1v8 ldo version, so ideally all I need to monitor to v...
Hello ST Team, We are using L5965 power management IC in one our projects. Currently we are in design phase and like to address one concern we are facing right now. So, if anyone could clarify, then it will be boon to us.Coming to the matter.In the b...
Hi ST Community / @Peter BENSCH I use my solar panel connected to the STEVAL-ISV020V1 to charge my LiPo battery. Everything works fine and it charges the battery. However since I am trying to charge it indoors, during night-time, my solar panel doesn...
Hello friends, i design ac/dc converter circuit using VIPER-319HD with eDesignSuite. One point makes me confused. In attached document, i am not sure these points are GND or not. When i look the datasheet, it seems that these points are related with...
Hello, please help me understand:1) What will happen if IN voltage less than the battery voltage? What voltage will in SYS in this case?2) Сan I connect SYS pin to IN? I'ts safe?
