L6470 ext switch-SW-erratic behavior
Posted on November 30, 2016 at 08:24The releaseSW command is behaving erratically.We have our own PCB based on ST design. On Power up GoUntil is executed. Limit Switch used is Omron EE-SX951-W. GoUntil never fails and SW input is detected correctly ...
L6470 abs_pos bit length not as large as literature claims? & busy pin ending early.
Posted on May 31, 2016 at 03:18From the literature, the abs_pos value is a 22 bit 2's complement integer. but when i move the position above 32768 (16 bit 2s complement maximum), the value resets to negative. I.e. the abs_pos value acts as a 16 bit ...

LD3985 question
Posted on January 19, 2017 at 21:03Hello to all!I have one more question about LD3985. I didn't find any information about limitations in high current modes. Output current of LD3985 is 150 mA. Can I use it for 250 mA load (for example) in continuou...
Preventing/Limiting inrush current on L7986
Posted on January 12, 2017 at 08:51Hi AllI am currently testing a power supply system with a bulk power supply backplane (30V, 12A) and cards that slot in on the backplane. The cards come in various different flavors (24V, 12V, 5V) all using L7986A ...
How find datasheet, characteristics and replacement for Bux tvs diode?
Posted on December 29, 2016 at 15:48I ask about one 12v tvs-diode of ST-electronics manufacture - Bux c543. It was found on sp0812n samgung 80 gb hddand was soldered through due to overvoltage from psu. Now I need to relace it, but I cannot find any...
