Hi,I'm using the STC3100 chip to get the coulomb used from the battery, using the REG_CHARGE_LOW registers,on the new board, I want to move to STC3117, but I don't see this register,Does anyone know how I can get this value? ThanksShamir
We want to develop a USB-C charger and we need to check the battery charge percentage of the device connected to the USB-C charger. The connected to de USB-C device can be a Smartphone, Tablet or PC.In our charger we are going to integrate a processo...
Dear Experts I am using 2s1p PA-LNB76-C17UL.4.1.R001 battery, Panasonic NCR18650BF battery for my new application. Output Voltage - 7.2VCurrent - 3350mAhI would like to know a compatible fuel gauge IC for it. Please pour your suggestions. Kind Reg...
Hello,I have developed my own evaluation Board for the STWLC98 Chip. When connecting the power suplly, the DC-Mode, which is on the IC when it is delivered, works in a correct way. But when I want to program the IC with the following firmware from th...
Hi Sir, Could you help share the equation of ILIMIT and RSET, ILed and RLED?I cannot find the equation in datasheet.Thank you.
Hello,I use ST's STDRIVE101 in a design to drive a three-phase BLDC motor and used the reference design EVALSTDRIVE101 as a design guideline. My design has a MOSFET switching frequency of 20 kHz and a MOSFET drain-source voltage between 36 and 42 V.I...
Is it possible to program the L6470 MIN_SPEED for a low value, set the acceleration and deceleration to zero and MAX_SPEED to zero to run at the set MIN_SPEED rate?
Posted on December 30, 2017 at 11:16I have a LED2001PHR based LED driver that is designed to drive a string of LEDs at 5.2V and 3A. When I apply power and the LEDs are connected, the LEDs flash for a fraction of a second and then go off telling me t...
Hello,I have a problem with STGAP2D and the interlock pin.If the interlock pin is on GND, SD and Brake are high, INB is high and the INA is high for 1s after this time 10ms low, than again 1s high and again 10ms low and so on.The output A is only low...
If the IC is powered by the battery, how does missing battery detection work ? I am working on a product which will have a USB interface and a single cell Li-Ion battery with charging circuit and a gas gauge. I need to take care of scenarios where th...
