power electronics - Does the IR2110 provides isolation?


The datasheet for the IR2110 shows this diagram:


enter image description here


Where vss is the digital ground. Does this mean that the block Vdd/Vcc LEVEL shift provides some kind of electrical isolation? Or it's the digital side of the chip still connected to the power side?



Answer



I don't see anything in the datasheet that indicates it provides isolation.


Normally for parts that offer isolation, the datasheet will include a rating for insulation voltage withstand, and also indicate safety agency approvals, such as UL or CSA.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
