How to Detect Open Load Condition Using L6470 Stepper Driver
Hello!I'm currently working with the L6470 Stepper Driver for my project. Despite thorough examination of the datasheet, I couldn't find any detailed information regarding the detection of an open load condition. If anyone has encountered this issue ...
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
STUSB4500 damaged during reconnection
Hi,We have a custom implementation based around STM32H7 and STM32F1.The application is powered internally by a rechargable 4s li-ion battery.We use USB-PD to charge the device, and USB 2.0 to communicate with the STM32H7 through an external ULPI-PHY....
Resolved! Question about Writeprotect (WP) for I2C EEPROM, eg M24M01E
For these EEPROMs there is a WP pin, which must be (active) low to enable write operations. I am driving this pin from an MCU, (ie. it is not tied to GND).Also these EEPROMs need some time after a write command to effectively write the data into the ...
