L9963T: Reception fails due to transmission line activity during power up.
We need help with a problem with the L9963T (SPI to isolated SPI transceiver).Please help us find the cause and solution.PROBLEM DESCRIPTION:We are using L9963Ts on each side of a communication link between two boards. Board #1 transmits to board #2 ...
Resolved! Clarification on Feedback Circuit of STEVAL-VP26K01B with VIPER26K
I am currently working with the STEVAL-VP26K01B evaluation board, which utilizes the VIPER26K IC, as part of an electric car project for Formula Student. During my study of the board's design, I noticed that the feedback is taken from a resistor divi...
Can't find STBC15QTR anywhere, it is out of production?
Just finished my design for wireless charging board with the STBC15QTR as charging controller. The chip marked as active production but i can't find the chip on estore.st.com, mouser or digikey. Where can i buy it?I could switch my design to STBC15LJ...
STUSB1600 can't work as source
Dear All, Hello everyone, I used STUSB1600 as the type-c dual role type power management. When it works as sink type, it is good. But when it works as source type, it doesn't work. I found VBUS_EN_SRC always keep high. This is my design schematic, co...
L6482 behaviour at high speeds
Hello,we want to use L6482 chip to substiture DRV8711 driver we have been using so far. However from our tests the driver does not behave equally as well. We took some oscilloscope screenshots showing that at high speeds the current provided to the m...
Resolved! Current sense on high side driver VNQ9025AJ
Hey,I'm planning to use this high-side driver in a project distribution module, but I'm having trouble fully understanding how the current sensing works.I've looked at the schematic, and I see a combination of two resistors, Rprot and Rsense. Is this...
Need DPAK MOSFET with high avalanche rating
We've been using the On Semi FDD8453LZ MOSFET (40V, 6.7 ohm, DPAK) in our motor control designs for many years, but this part is now EOL. We're looking for a suitable DPAK replacement. One critical parameter is the single pulse avalanche energy, wh...
SPV1050 BATT_CHG output
Dears,There is SPV1050 in my circuit. Works without MPPT, boost mode. The problem concerns BATT_CHG state. Documentation says BATT_CHG output reflects DC/DC converter state, i. e. it is active (low) when DC/DC converter works. Simply saying:1. When i...
L9916 Device Program Mode
Trying to switch L9916 to device program mode.Followed every instruction in Application Note, but failed I2C communication with the device (L9916 does not generate acknowledge - so it seems, that the initial sequence failed?).Could someone give me a ...
VIPER319XD thermal and loss characteristics
I have reviewed the VIPER319XD datasheet and the Power Supply Design Tool, and I have a few questions about this IC:The datasheet only provides RthJA (80°C/W) and does not specify the RthJB value. In another datasheet for the same package, I found Rt...
