Re: STWBC86 -> Writing FTP (Few Times Programmable) from header over i2c?
@saleh1000, There is no mention on how to actually perform writes to the FTP (Few Times Programmable) memory in the Data Sheet.
Resolved! STWBC86 -> Writing FTP (Few Times Programmable) from header over i2c?
Hello, Looking through the data sheet for the STWBC86, there doesn't appear to be a way to write to the FTP (Few Times Programmable) memory, nor save individual configuration register values over i2c. Any register values are only written to RAM and ...

I am having difficulty locating information regarding some diodes. These diodes are either zener or TVS.Can anyone help me identify it? A link to a cross reference information page would be really helpful. Will be looking to source them for repair pr...
Stepper motor moves when touched
I'm currently controlling a closed loop stepper motor with an Arduino Uno R3 via the CL86 stepper motor driver. I also connected 2 buttons with pull-down resistors with which I can, for example, rotate the stepper motor by 90 degrees in one direction...
STUSB4500 Default PDOs without I2C
Hi, We like to use the STUSB4500 without having it to progamm via the I2C. So we need to use the standard configuration. If I understand well, these are has 3 PDOs: 5v/1.5A - 15V/1.5A and 20V/1A.However, the 20V/1A is too high. Is there a way to prev...
81AB-C2A
Hi, I've been tasked with repairing an old analogue/mechanical instrument cluster from a Ford Transit van. The fuel and temp gauge instrument was not working. I determined that the voltage regulator wasn't working. It has labels of '950A' and '81AB-C...
