STWLC89 application related
Hi,Since we haven’t received the datasheet yet, we’d like to confirm the following information:If the receiver side (RX) uses the STWLC89 15 W solution, what is the corresponding 15 W transmitter (TX) model?Which Qi standards are supported by STWLC89...
Resolved! About High Side Driver Selection
Hello everyone,I am finding to drive for 4 cabin lock. For this, VNxxx or VNQxxx series help me. I don't need high current. It is 1 amper per channel(per output. I'm looking for a chip that will not cause any supply problems and will be produced con...
Resolved! STPMIC1D Boost bypass
HiIs it possible to bypass the boost by applying a 5V voltage directly to BSTOUT (VLXBST is left unconnected)?Thank in advance for your reply
Resolved! Search for datasheet
I can't read référence; I am asking if this component is a zener Diode? And I'm looking for any équivalence
ACS, ACST negative voltage schematics ?
I found the ACS108-6SA that seems to fit my needs. 1) I will control the gate with my stm32G0B1 uC. I really don't understand why I have to connect the 24VAC Neutral to the +3.3VCC of the MCU ! It sounds like dangerous no? i can understand that the...

Hello!I am currently designing a flyback converter with the altair04-900.The .lib file in the spice model folder is encrypted. I cannot open it neither with Altium nor with ltSpice.I would like to know, which simulation software can decrypt it? And, ...
Viper12, AC-DC non isolated Buck converter 5V 60mA
Hello, I'm considering using Viper12 to 3Phase AC/DC non isolated buck converter 5V 60mA Vout. I found some application notes like AN1357. But is it reliable? Or will it cause problems in long-term operation? Has anyone experienced it before? Thanks,...
Resolved! SCTWA70N120G2V Ron data
I want the specific Ron data corresponding to different VGS values (e.g., 8V–15V) when the MOSFET switch SCTWA70N120G2V is in the linear region.
Output capacitor selection for LD1085D2M-R
Edited by a ST moderator: Update the title and the content with the part number Hi,I'm using LD1085D2M-R regulator. There is no certain information about output capacitor ESR limit value for stabilization. -Input : 5V -Output : 4V @3A -Desired Outpu...
BTA41-600BRG stuck ON in some cases
We are using BTA41-600BRG triacs on our temperature control boards to turn on 240V tank heaters. The tank heaters are 1500W, 3000W, or 4500W depending on the unit model and operate at 240VAC. The circuit we are using is attached. We use a FOD4108 dri...
