Posted on October 18, 2016 at 19:38I am using STMicroelectronics' Rad-hard 14-bit 20 Msps A/D converter RHF1401 in one of my electronics boards. After analysis, I have discovered that my power supply to the AVCC (pins 41 and 42) may be susceptible t...
Posted on April 27, 2016 at 05:06Hi ,I would like to use the quadrature encoder for speed / Position feedback in order to get slow speed FOC control. When I enable that I have a pin conflict on A0 (encoder interface and Phase current) and A1 (encode...
Posted on October 10, 2016 at 18:39I am searching for a simulation file for the L4978, and I'm having difficulties finding one. Do you know of anywhere where I can find a file? PSpice or LTSpice is preferred.
Posted on October 10, 2016 at 08:46In my application used L6562A as PFC pre regulator. At initial startup observed overshoot at output,so mosfet gate is disabled. It is switched ON again once DC link capacitor discharged to it's regulated value.To d...
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...
