Part Number: UCC5870-Q1 Dear team,
1. If one fault is masked, then nFLT pin won't pull low. Does the FS_STATE_XXX operate? For example, if VCC1 OVLO fault is masked, and we set bit14=0. When this fault occurs, OUTH/OUTL will have no action due to being…
Part Number: UCC5870-Q1 Hello,
I am using the UCC5870-Q1 A/D converter with "Edge-Sampling-Mode" configuration.
I have to read some ADC data after the device enters the "Active" operation mode for several system checks before switching-on the…
Part Number: UCC5870-Q1 Other Parts Discussed in Thread: TEST Dear team,
1. Could you please tell me our device how to monitor gate voltage? We found that when we disconnected the resistor Rgon between OUTH and Gate, our device will report GM fault.
2.…
Part Number: UCC5870-Q1 Hi Team,
Customer found 2 different formula for calculating VGTH.
Which one customer should be using, thanks!
Andrew
VGTH = VADCDATA8 × 8
VGTH = DATA_OUTH(decimal) × 3.519mV
Hi Tobias,
Thank you for your patience.
Tobias Haerter said: 1. I could no read the TX CRC data from the CRCDATA register. The values change every time. What is wrong at my implementation. I write to the TX CRC register and then read it, but the read value…
Part Number: UCC5870-Q1 Hi Team,
Customer uses 6 UCC5870 on the board - as U/V/W.
When read back ADCDATA8, customer found only one out of 6 has value, the rest shown 0.
Customer mentioned they did Address-based H/W connection, and did addressing for each…
Part Number: UCC5870-Q1 Dear TI experts,
we are currently evaluating a UCC5870-Q1 gate driver IC in combination with SiC MOSFET. Our goal is to monitor the voltage of the gate of the mosfet as close as possible to the real device due to safety reasons…
Part Number: UCC5870-Q1 hi,
Customer would like to decrease the RC filter frequency to improve the noise filter performance (RC to be around few ms), understand higher R cause poor accuracy and higher C reduce the response time.
Is there any limitation…
Part Number: UCC5870-Q1 Dear team,
Could you please help answer below two questions? Thanks!
1. Could you please tell me whether our Bootstrap function can support OUTH remains high for 2 hours? In my understanding, the bootstrap cap needs to be char…
Part Number: UCC5870-Q1 Hi Experts,
Our customer mentioned that the available Simplis model on the UCC5870-Q1 webpage is unfortunately not complete. Several submodels are not included.
I could not verify this concern as I do not have the software to do so…
