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...
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...
Resolved! VIPER31 switching losses
Hi,I would like to use the VIPER319HDTR and would like to check the thermal to see if Tj will be an acceptable value.However, the switching losses of the internal FET are not mentioned. Is the switching time of the internal FET known? Or is there ano...
Custom Wireless Charger Based on STEVAL-WBC2TX50 - Qi compatibility?
Dear STMicroelectronics Support Team, I have built a custom wireless charger based on the STEVAL-WBC2TX50 evaluation board, following the provided BOM and schematics. I successfully flashed the STSW-WBC2FW_V1300 firmware into the STWBC2-HP controller...
