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: UCC27282 , UCC21551 Tool/software: Hi Team,
Customer is doing worst case calculation for UCC21551 and UCC27282.
Can we can provide minimum and maximum value for ROH, RNMOS and ROL of UCC21551…

Hi,
am planning to use ucc21551-q1 as my dual isolated gate driver for the SiC (SCT018H65G3AG) based PSFB , suggest me how to configure this driver to get…
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-Q1 Tool/software: Hi team,
Is there absolute max ratings for the pulsed current for this device at OUTA and OUTB for VDD=15V?
regards,
Part Number: UCC21551-Q1 Other Parts Discussed in Thread: TINA-TI Tool/software: Hi expert,
There have an example in datasheet for application circuit with negative bias, see below.
I am not quite understand why it says determine by duty cycle? Need…
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: Hi Expert,
We are estimating the power for the driver using the equations from the UCC21551-Q1 datasheet, including a 50% tolerance. We are employing a Negative Bias with a Zener Diode on the Iso-Bias Power Supply…
Part Number: UCC21551-Q1 Tool/software: Hi Expert How many dedicated VDD supplies are required for the UCC21551CQDWKRQ1? Is it possible to drive the UCC21551CQDWKRQ1 with a single VDD supply for both switches, or are two dedicated VDD supplies needed…
Part Number: UCC21551-Q1 Other Parts Discussed in Thread: UCC21551 Tool/software: For calculating Gate driver power supply ( UCC14240) requires IQ_DRIVER_VDD, IQ_DRIVER_VEE. But UCC21551 datasheet only has I Q_DRIVER_VDD. My VDD is 18V and VEE is -4V…
