Stbc03. What will happen if IN voltage less than the battery voltage?
Hello, please help me understand:1) What will happen if IN voltage less than the battery voltage? What voltage will in SYS in this case?2) Сan I connect SYS pin to IN? I'ts safe?
Resolved! About VNL5030JTR-E
Thank you very much for your help.My name is Ichikatai, Designe Engineering Department, NIKKI CO.,LTD.Regarding the VNL5030JTR-E productI believe that high melting point solder (lead 85% or more) is used in the semiconductor chip part as an exemption...
exposed pad
“What could happen if the exposed pad of the LD39200 is not properly grounded? Could it affect its functionality?Is there any limitation regarding the reflow temperature for the LD39200, considering that everything seems fine initially but only 0.4 V...
Driving GaN FET Transistors with the STDrive101 / STSPIN32 range
Hi,Is it possible to use a STDrive101 to drive a GaN FET give the typical 6V Vgs max rating of these devices?I read the datasheet reference to 5.2.2 Externally provided gate driver’s supply voltage to see if we could home how reduce the 12V LDO to sa...
Resolved! STM32F405 behavior when VCap pins aren't connected
Good morning,I'm using STM32F405 for my embedded project and this PCB version showed itself a real MCU killer... So far, it has already burned 4 MCU. Here's my situation. It's not my first time designing using an STM32 (I've already used STM32F103), ...
Different reading on shunt depending on motor direction
We have based this board off of EVAL-L99H02QF.We are having a difference in current reading on CSI2. We have 2 shunts, and the one that goes to GND R38 in my picture has a different reading whether motor is going one direction or the other. We canno...
PowerStep01 step clock mode, maximal acceleration
I have a motor that is capable of of an acceleration of more than 1'000'000 steps/sec^2. However, I cannot this high acceleration because the max. acceleration the internal motion engine of the PowerStep01 allows is 59590 steps/sec^2 (ACC Register, S...
Resolved! WLC poller/listener development boards or and app notes
I am lost and confused between the wireless charging topic when it comes to development boards. Which ones should we order in order to test the working principle of the wireless up to 1W charging?Is ST25R3911B-DISCO the one to use as the WLC-Poller? ...
Looking for information on how to estimate lifetime of a Triac
Hi I'm looking for some help in estimating the lifetime of a triac for a customer.I have thermal models and have performed lab tests to estimate junction temperatures and case temperatures. I expect the Junction to reach 115C peak. The Case to be 10...
Resolved! Need help IDing a TVS
I have a PCA with a blown TVS. The markings are: ST e3 G3BA◇YZ521I've seen TVS datasheets with markings starting with 3BA, but the diamond symbol is throwing me off. Can you assist?
