Part Number: TIDA-00917 How much Lg will CM choke introduce to the gate loop?
The design BOM shows the part number is B82789C0/S0. According to that, Lr of 11uH shows Lstray,typ of 60nH. Does that mean the introduced Lg is 60nH?
Part Number: TIDA-00917 Other Parts Discussed in Thread: ISO5852S , ISO5851 Hiii,
I am trying to implement the auto reset circuit (TIDA-00917, page no.11) in my gate driver. But when i analyzing the circuit i got a doubt. when RDY pin is low , the diode…
Hello Tonglei,
Thank you for reaching out.
I'm currently unable to provide the exact design files or evaluation PCB for current booster topologies you're requesting, but I recommend taking a look at the TIDA-00917 reference design. It's an ISO5852S…
Part Number: UCC21750-Q1 Other Parts Discussed in Thread: UCC21750 , TIDA-00917 Tool/software: Hi TI team
Need your expert team support on following:
Our gate drive requirement is 20A
We selected TI UCC21750QDWRQ1 ( 10A) and using Current buffer…
Hi Subhransu,
Thank you for the LMG3650EVM-113 suggestion.
I am afraid we can't design around a part that is in pre-release state.
Do you know when they will be available? The LMG3650R025 part?
We are considering moving away from using GaN…
Part Number: UCC21710 I am using UCC21710 to drive 2 SiC MOSFETs in parallel. Based on the discussion in another link of e2e ( https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system…
Ryu,
Yes this is possible, and not uncommon.
each IGBT should have its own seperate external gate resistors placed close to each IGBT pins.
As Collectors/emitters are shorted, there only needs to be one desat HV diode going to the shared collector…
Hi, Yi,
If you apply a voltage > VBE to a bipolar transistor, you will allow current to flow between its collector and emitter. So, if the gate voltage has a transient on it due to switching noise, the two transistors will work as clamps to clamp that…
Part Number: ISO5852S Other Parts Discussed in Thread: TIDA-00917 Dear Team,
I have a question about the specification of t_mute of RDY pin of ISO5852S. In the ISO5852S datasheet, page 20, Figure 46 shows the DESAT, OUTH/L, /FLT, /RST Delay. In this…
