Hi,
We would like to inquire about the following three technical topics regarding the UCC21551 isolated gate driver:
The UCC21551 is offered at a significantly…
Hi Chase,
Chase Jeong said: 1. About bypass capacitor, You said that no capacitor needed, but my customer wants to add bypass capacitor.
Could you recommend the value of bypass capacitor under 1nF?
If the customer wants to add a capacitor there…

Part Number: UCC21551-Q1 Other Parts Discussed in Thread: UCC21551 Tool/software: Hello,
In my application, only one channel of UCC21551 driver is used (INA - OUTA - VCCA / VSSA). How would you configure the outputs of channel B? OUTB, VCCB and VSSB…
Part Number: UCC21551-Q1 Tool/software: We are using a PFSB topology with HVDC voltage=400v & Fsw=80KHz .Gate driver is used to drive IPDQ65R040CFD7A coolMos. A 15V Supply provided to VDDA & VDDB . The Bootstrap diode used is US1MHE3 with VRRM=1000V &…
Part Number: UCC21551 Tool/software: Hello TI Community,
I’m currently simulating a full-bridge gate driver circuit using two UCC21551 isolated gate drivers in PSpice. However, I’m running into a problem where the OUTA and OUTB outputs of both UCC21551…
Part Number: UCC21551 Tool/software: Hi,
Low-side outputs work fine, but high-side outputs not turning on. On U18, I turn on low side driver (Vg Q5) for 7.5 ms, then off for 1 ms, then turn on high-side driver but simulation gives an output only for…
