Part Number: ISO7821 Dear experts,
My customer want to use ISO7821DW in their product. The maximum working isolation voltage is 2000VDC<2121VDC, so the ISO7821DW could meet the spec.
And they need add the 4000VDC/1min between two sides. I find the…
Hi TTD,
Thanks for your response.
ttd said: It would be helpful if you could theoretically explain why TI isolators are resistant to magnetic fields.
The devices that are made up of large inductive circuits are usually prone to external magnetic fields…
Part Number: ISO7821 Hi team,
I got a question about VCC1 and VCC2.
Does ISO7821 work normally when different power supply are used for VCC1 and VCC2?
(e.g. VCC1=3.3V, VCC2=5V)
Best regards,
Yuto
Part Number: ISO7821 Hi, TI-engineers,
I'm J.Komura of TI Distrbutor TED and we received question from our customer for TI indicated FIT's values on Web. Customer are examining several deveices' FIT values for their new applications. Then below…
Part Number: ISO7821 This thread states that as of December 2018 the certifications for the ISO7821 were complete. However, the datasheet still states "Certification Planned". When will the datasheet be updated? I expect my certification lab to require…
Part Number: ISO7821 Hi,
my customer choose ISO7821DWWR in their system to achieve isolated UART communication between C2000 and STM32F107.
C2000 is controlling a 1500VDC solar inverter system.
And they need to achieve reinforced isolation between C2000…
Part Number: ISO7821 Hi Team,
Good day.
My customer wanted to use ISO7821 for isolated 5V to 5V conversion and use ISO_5V to the USB side. Can he connect a window compactor at Input B (at isolated side) which will detect the range of ISO 5V and depending…
Part Number: ISO7821 Hi Team
My customer is using ISO7821FDWWR with 1500Vrms, f=20kHz.
They want to know the lifetime of ISO7821FDWWR with the conditions mentioned above.
I've got the TDDB test information for 3500Vrms, f=10kHz from the thread below and…
Part Number: ISO7821 Hi Team
My customer is using ISO7821FDWWR and they had a noise test to a board which ISO7821FDWWR is equipped on it.
But abnormal heat generation of ISO7821FDWWR occurs.
Even if the noise apply is stopped, abnormal heat generation…
