Part Number: UCC27517A-Q1 Tool/software: Hi team,
We are using UCC27517A-Q1 and some other parts of TI in our power supply design. We followed MIL HDBK 217F for the MTBF and FIT calculations.
When we verified the MTBF and FIT of the same part in the…
Part Number: UCC27517A Other Parts Discussed in Thread: UCC27282 Tool/software: TI相关工作人员你好，我在使用UCC27517AQDBVRQ1 器件驱动直流电机时遇到了一些问题;
1.栅极驱动器总是烧毁，我们初步判断是电机堵转时的大电流烧坏，（电机正常工作时最大电流可达6A），已做好散热措施;
2.栅极驱动器UCC27517AQDBVRQ1目前已经失效两三次了，失效现象是：芯片供电及输入信号正常，但芯片无输出;
原理图如下…
Part Number: UCC27517A-Q1 Other Parts Discussed in Thread: UCC27517A Tool/software: Dear Rubas,
As you know we are using TI gate driver ucc27517A-Q1 ic with our PFC+LLC controller to drive PFC mosfets . PFC out put is 390V - 2.99A.
In previous mail we…
Part Number: UCC27517A-Q1 Tool/software: The below total component FIT rate should be sum of die FIT and package FIT. Could you please help correct it?
Hi Aditya,
I understand the case that the external MOSFET is not damaged, and it is the internal MOSFET that is damaged.
However, I want to try to debug more in the case that there is more damage. Can you conduct a diode test from VDD to OUT and from OUT…
Hi Revathi,
Since it's been almost a month with no activity, I am assuming the problem has been solved, so I will be closing the thread. Feel free to reply to reopen if you have any issues.
Thanks, Rubas
Part Number: UCC27517A
I am using UCC27517A as gate drivers for high side and low side mosfets.
1) For the High side mosfet, the HS pin is connected to GND and IN- of UCC27517A. As the HS pin is switching node and 400V appears on it , can IN- and GND…
Part Number: UCC27517A Other Parts Discussed in Thread: UCC27511 , LMG1020 , UCC27614 Team,
My customer needs max/typ/min source/sink current at VDD=5V, since datasheet describes +/- 4A as typical at VDD=12V. Could you please clarify?
Best regards,
Ko…
Part Number: UCC27517A Other Parts Discussed in Thread: UCC27517 Hello all,
I have designed a simple circuit to turn on/off a MOSFET using the UCC27517 gate driver. The schematic is below.
Using a waveform generator, I am applying a pulse signal with…
