Power management

I am designing a Crowbar circuit using TRIAC BTA series. Intention of the crowbar is to break the circuit when the applied voltage is above 295V AC 50Hz.

When I had tested the attached circuit initially the TRIAC BTA12 damaged in surge pulse (IEC61000-4 - @2KV pulse) as well High voltage test aroung 300V AC 50Hz. 10A Slow blow fuse blown (little fuse 215 series) but it is not protecting the TRIAC.I su...

PowerStep01. What is the proper way to connect protection diodes for the two in chip regulators? Also, is it ok to have 3.3V power and no Step Voltage? I have added a copy of the proposed layout. Any help is appreciated.

What is the problem in circuit design with A6986 .

Hi. I designed the power conversion circuit with A6986.​After soldering of this pcb, I powered 24V on power line.​And the VIN pin(#15) was damaged.​I have no idea what is the problem.​when I design the circuit, I consulted the manual, and eval. board...

I am facing problem while driving L9945 development board, when I try to drive output of eval board using NON pins, 7 and 8 output work good but when I try to get output from other 6 remaining pins. Can anyone help me to get out from this condition.

I'm looking for ST eZ12042 IC datasheet

Hello, I have switching power supply with some IC from STMicroelectronics with ST eZ12042 marking on them but i can't identify them and find datasheet. I will be grateful for any help​Thanks in advance!

Why two mosfets and two diodes were chosen for Bridge rectifier instead of 4 diodes in 3KW grid-connected PV system, based on the STM32F103xx STM reference design AN3095.

Hi,i am desining an inverter using STM reference design AN3095.i happen to notice that the bridge rectifier section has been implemented using two fets and two diodes.Why is that so?What is the significance in such a method?Why din't they use four di...

Powerline Communication IC

Hi,We have built devices that run on batteries and serve a specific task. For the future we also want to offer a wired solution, for better user experience and more features, that would drain the batteries faster. Since the wired solution already re...
