Posted on September 28, 2016 at 09:45I am not getting any response from the chip. The microcontroller I am using is a Parallax P8X32, giving me full control of the SPI signalling. I am using Mode0, doing a: CS high, CS low, clock out xD0 (get status...
Posted on April 15, 2016 at 17:06,Hi,I am currently working on STC3115.I am facing problem with it.The slave i mean STC3115 is not getting detected when i do i2c test.My platform is linux.I have checked the voltage levels,itseems all are fine.SDA an...
Posted on July 26, 2016 at 10:33Hi Sir/Mdm,I have few questions regarding STC3115. After implementation, I have noticed that voltage & current measurements are working properly, however the SOC value is never updated. 1. Is it normal? 2. Does the ST...
Posted on March 30, 2016 at 10:29We need to settle a difference of opinion interpreting the data sheet for the VND5T050AK-E, dual channel high-side driver IC. We agree that when you provide a normal load, the CSn output acts as a current source whos...
Posted on March 21, 2016 at 12:33For a project I'm working on I have to be able to switch the polarity of a peltier element (or other device) and be able to linear control the current through the peltier.I didn't want to put a normal relay in this s...
Posted on August 30, 2016 at 21:00Hello,The datasheet of the L6924D mentions on Page 19 that the the current injected in REND is proportional to ICHG. It also states that the voltage across REND can be used by a microcontroller to check the charge s...
Posted on August 30, 2016 at 19:21Hi. I designed the power converter which is supply from the photovoltaic cell ( Umax = 5.5 V / 1 W) on a SPV1040. The problem is that the system did not stabilize the output voltage.The output voltage is proportiona...
Posted on August 18, 2016 at 14:44Hi all.I recently developed a system that uses the PowerSTEP01 devices. I had great trouble getting hold of the devices when I originally prototyped the design. Now I've come to order another batch and no body seems...
Posted on August 12, 2016 at 00:39Hi, I design a battery charger with SPV1020 and DN0023. It's works ok. So I connect trought SPI with a uC. I read the different registers succefully. But I want to know what is the scale for register 0x04 (Read Curr...
Posted on August 02, 2016 at 08:37Hi All, We are using A6986 ic our board to convert 12V to 5V, but ic itlsef taking more current, its 3.50 mA. Here i am attaching the my part of schematic. Kindly look at it and let me know what may be the problem.
