Hi! I need a SPICE model for T2535T-8I. I couldn't find it anywhere. Please help! Thank You!
L99LDLH32 modify Responder ID issue
Hi everyone,Good day!I'm currently working on modifying the Responder ID using CAN FD communication.I initially had a firmware running on an MCU that was capable of modifying the Responder ID. My goal now is to analyze the CAN FD communication from t...
STUSB4710 on a 3 port USB hub
Hello,I want to use 3x mentioned devices in a usb hub to deliver pover to peripherals.Does anyone has experience with something like this? Can it negotiate with three different devices or it will cuse some trouble.? Best regards, Mrdjoni
Viper35 waking up issue.
Hello,For the past few days, I’ve been trying to operate the VIPer35 quasi-resonant offline high-voltage converter, but I haven't been able to get any output. I attempted to bypass or disconnect the output of the PC817 optocoupler and also tried sho...
STP40NF20 Drain voltage oscillation issue
Hi, We have build a led driver circuit using STP40NF20 -- 2 nos in parallel, the issue i am facing oscillation issue in Drain pin (Vled ), So kindly support in this regards..
ST1PS02D1QTR VOUT2 Output Discharge
I have ST1PS02D1QTR (output discharge disabled variant). However, I am observing that if AUX = low but external 1.2V is applied to VOUT2, I get power dissipation that seems in-line with output discharge resistance on VOUT2. My question is this: does ...
L4931 Output Capacitor
A design I am debugging is utilizing Y5V dielectric capacitors on the input and output of the L4931. There is a 2.2uF capacitor directly at the output and another 2.2uF capacitor on the other side of an ~4 Ohm resistor that analog supplies are used o...
STEF01 Output Clamp 32V Max?
I have recently designed the STEF01FTR into a design that sits on the main input rail. The input is specified to run from 9V-48V. As a result the output VClamp is set the 52V max by setting R122 to 560K and R126 to 10K. When our initial FAI boards ar...
STUSB4500 I2C hot swap
We're using this controller in our project and have the VCC pin tied to VBUS so the device does not pull power from the battery when USB is not connected (it was pulling ~125uA which is too much for our battery life as the main power is not turned of...
STCS1A
Hi I am using STCS1APUR to drive 10LEDS IR, (MTSM5116MT2-BK), circuit belowcurrent should be 1A as of f/b resistance, enable gets turn on as sson as the STM32 MCU comes up, supplying a 3.3VDC PWM though the MCUissue:the voltage drop across the led is...
