Resolved! Clarification on Maximum Voltage Limitation of EVLSTGAP3S6S Board
I am planning to purchase the EVLSTGAP3S6S evaluation board for my research. While reviewing the datasheet, I noticed that the board is specified to support a high-voltage rail of up to 520 V, limited by the MOSFETs and capacitors. However, I observe...
[STWLC38] Operating Frequency and ASK modulation cycle
Hello,I'm developing a Qi compliant product (Not getting Qi.) using STWLC38JRM.Please respond on Operating Frequency and ASK modulation cycle to get back to the testing agency.[Operating Frequency]Qi standard defines the operating frequency from 110 ...
Resolved! device recommendation for 208VAC, 480VAC, 40A AC heater switching application
Application : We are developing a AC switching circuit using dual MOSFET configuration. The application is for driving the 208VAC, 480VAC, 40A AC heaters to control its temperature.1. Is it preferred to use MOSFET or IGBT for this?2. Which MOSFET ser...
L7987L Not working as expected
Hello All,I am using L7987L to generate +15V from 24V. I have 10 same boards wherein I have used the same circuit (see below), I am able to generate 15V for 2 boards but in rest it is generating 1.22V only. R191 is 6.8kohm and diode D36 is US1M-E3/61...
Resolved! EVLVIPGAN50PD Modification for Standalone 12V Power Supply
Hi Sir, I would like to explore a specific use case that deviates from the standard design. My goal is to modify the EVLVIPGAN50PD to achieve a fixed 12V output, bypassing the USB PD negotiation functionality entirely. My intention is to utilize only...
Mastergan5 - Switching losses
Hi,I'm interested in the Mastergan5 IC.To evaluate it for our use case in a Class-D amplifier we need information about switching losses.These are commonly provided by suppliers of half bridge ICs by providing the Eon and Eoff values over switching v...
Resolved! STM6600 Implementation Queries
Hi,We are implementing STM6600 push button controller for our design and we have below queries. Is there any pull up connected to PS hold pin, can I connect this directly to 3.3V logic MCU.For variant STM6600DU25DM6F, tON blank is 11.2s, Do we need t...
STPM32 triggers interrupt for non masked bits.
Hello,I use a STPM32 on a battery charge system. The STPM32 is associated with an ESP32 module.The driver used is from ST (V1.0, 17 may 2016).I want to detect some defaults with interrupt, and I configure the interrupt mask only for current and volta...
L9524C Control Input Signal Max. Duty Cycle Value
I have already using L9524C IC for glow plug controller. I have to must to learn that what is the maximum duty cycle value of Control Input (CI) PWM signal?And if I have apply continuous HIGH signal to Control Input pin, how L9524C works? Freq. is 40...
Clarification on STUSB4710QTR Configuration for 5V/5A Power Source
I just need some clarification regarding the STUSB4710QTR.I'm designing a USB-C power source where a USB 2.0 hub will supply 5 V/5 A to a USB device. The connected device is a USB cellular modem, which typically draws a continuous 5 V/3 A, but requir...
