Posted on December 13, 2017 at 08:36Hi. I would like to set a battery float voltage to 4.1v (to extend the life of the battery). Looking at the datasheet for the li-ion battery charger STBC02, it looks like this can be adjusted but 4.2v seems to be ...
Posted on December 13, 2017 at 06:34Hi,To serially control Brushed DC motors using STSPIN32F0A.I would like to connect a bluetooth module HC-05 through the USART1's PB6 and PB7.What are the connections I need to give for the brushed DC Motors?How ma...
Posted on December 11, 2017 at 19:55In the STEVAL-ISB035V1 Manual (UM2132), the schematic and ball-out refer to the STBC02 instead of the -03. Also, on the board, both R11 (in the '02' section') and R8/ R13 (in the '03' section) are installed. This ...
Posted on September 28, 2016 at 19:51Hello,We are using a STC3115 in one of our designs. The problem is that it does not start up.I read: https://github.com/st-sw/STC3115GenericDriver/wiki/STC3115-FAQIt looks like the problem is that the BATD is 'hi...
Posted on May 15, 2017 at 09:54We are having cases where Fuel gauge IC (STC3115) get stuck during Long run. It has been found that SDA remains low in this case. In order to recover from such situation I am planning to reset the fuel gauge.Is there a...

Posted on November 16, 2017 at 13:06Hello,On my nucleo-l073 board, my software can run in stop mode and consumes only 3uA. I decided to make my own PCB but i can't figure out why the consumption can't reach 3uA. Actually, i'm running around 25uA wit...
Posted on November 29, 2017 at 09:18Hi,As mentioned, input voltage is 48VDC and there is up to 40A available. I would like to be able use all this to drive our motor (custom IPM). I am free to design the driver board with 3-shunt current sensing and...
Posted on August 15, 2017 at 11:49Hello,I am using 'L6482H discovery board' design example for L6482 chip, for making my own pcb board, using the same mosfets, etc.At this moment, my board runs really well with 2A stepper motors and 80 mili-ohm R se...
Posted on November 07, 2017 at 12:32Hi everyone, I am planning to use sic mosfets in inverter application(2 level or 3 level) and I searched some manufacturer and prices, I saw sct30n120 and ST says ' Very fast and robust intrinsic body diode (no ne...
