Resolved! Power good (PG) pin on LD39100
HiI am looking some guidance how to use the PG pin to indicate the power good mode with fixed versions of LD39100. (3.3 and 1.8V versions.) I plan to use the 3.3V output as an input for the fixed 1v8 ldo version, so ideally all I need to monitor to v...
Regarding REF pin and LDO pin outputs
Hello ST Team, We are using L5965 power management IC in one our projects. Currently we are in design phase and like to address one concern we are facing right now. So, if anyone could clarify, then it will be boon to us.Coming to the matter.In the b...
Resolved! STEVAL-ISV020V1 - min required voltage to be operated
Hi ST Community / @Peter BENSCH I use my solar panel connected to the STEVAL-ISV020V1 to charge my LiPo battery. Everything works fine and it charges the battery. However since I am trying to charge it indoors, during night-time, my solar panel doesn...
Resolved! VIPER319-HD AC/DC Design
Hello friends, i design ac/dc converter circuit using VIPER-319HD with eDesignSuite. One point makes me confused. In attached document, i am not sure these points are GND or not. When i look the datasheet, it seems that these points are related with...
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...
