MB1419 - RC snubber design
Hey everyone!I am trying to understand the snubber design for a 3 phase inverter to reduce ringing. What is the difference between placing the RC snubber:- between each phase output and ground (3x RC snubber)- between drain and source of every mosfet...
RS485 Communication disturb in run time
In one project we are using ST1480ABDR (Transceiver) and Baud rate is 115200. One master and 19 Slave connected in star topology. Please find attached reference termination resistor on both side, one at master and only one at slave. Run time our comm...

Need clarification on PCN
Will you please confirm on below part numbers that whether there will be any change in electrical parameters of the affected MPN depending on their PCN. For that do we need to verify any electrical parameters again? Part TypePCN Tracking NoType of C...
Technical issues related to RF transistor SD2933
We want to use this transistor to drive piezoelectric ceramics at 900KHz, 1.7MHz, and 3MHz, which requires about 50W of power.I have the following questions and need help:1. Can this transistor be used at a frequency of 900kHz? Can it only be used in...
Reading STUSB4500 USB PD status via I2C
The USB PD status register is a combination of 4 registers.The question is when read, are they interpreted as big endian or little endian?so 0x91 0x92 0x93 0x940x91 = bit 0-7, or 28 - 31?0x92 bit 8-110x93 ...0x94 ...The manual and programming guide a...
STUSB4500 connect to USB type A but The Mosfet it don't actve for get 5v
in my project I use STUSB4500 for get power delivery from USB_C but we need connect to USB_A for get power (5v) sometime but MOSFET not active and I can not to get power form 5 vhow can I solution this problemThank you
