Hi Joshua,
The 160MHz shouldn't be from ISO7820, the carrier signal used in the device is at much higher frequency. The power level of the carrier signal is very low and it doesn't appear in any of the radiated emissions test including CISPR 22 and…
Other Parts Discussed in Thread: ISO7820 Dear all,
in the ISO7820 datasheet the package option DWW is mentioned and drawings exist also. But I cannot find any order information for that package. Maybe I am blind, but please can you tell me wether this…
Part Number: ISO7740 Other Parts Discussed in Thread: ISO7820 Hello,
We discuss internally the lost of hvdc (high voltage) isolation due to iso7740 (on also on iso7820...).
I guess that the lost of isolation is very rare (reading different document…
Part Number: ISO7740 Other Parts Discussed in Thread: ISO7820 Hi,
Yes, we've already seen the TDDB plot and we will continue to discuss that, but idealy we need Failure Modes and Distribution with the item 'lost of isolation'. Is it possible for TI…

Part Number: TIDM-02002 Other Parts Discussed in Thread: UCC21530 , PMP21553 , , PMP21495 , PMP21561 , ISO7820 , PMP21999 Hello!
I have been trying to pitch UCC21530 as an isolated gate driver in an HEV/EV application and have run into some confusion…
HI Martin,
Welcome to TI E2E forum!
I took a quick look at Table 7 in IEC 61010-1 and I do see that creepage required for 1000Vrms working is 5mm for basic isolation and is twice (10mm) of that for reinforced isolation. While clearance requirement…
Other Parts Discussed in Thread: ISO7820 Hello Team,
Customer is looking for the digital isolator as below.
VISO = more than 3000Vrms
Clearance, L(101) = more than 6.4mm
Creepage-distance, L(102) = more than 9.6mm
However, the creepage distance…
Alejandro,
ISO7420 (device from an older family) may work in your application but we have much better & robust devices to choose from. If you would only need basic isolation you can choose ISO7320C and if you were to have reinforced isolation please…
Hi Adi,
Yes, it is possible to extend this to achieve 3-phase voltage and current measurement. There are multiple ways of implementing three phase measurement using shunt and voltage divider.
1. If you are using low side voltage measurement, you can…
