Part Number: UCC5870-Q1 First off we are getting a bunch of INT_COMM_SEC_FAULT and some INT_COMM_PRI_FAULT when running IGBTs at high voltage and currents so was wondering if there were any tips for avoiding that (layout recommendations, capacitor values…
Part Number: UCC5870-Q1 We are using the UCC5870 and are getting INT_COMM_PRI_FAULT and INT_COMM_SEC_FAULT sometimes.
Can you give us a little more information on what causes each fault and the difference between the two faults?
The datasheet seems to…
Part Number: UCC5870-Q1 Hello Experts,
What is the minimum time taken to send six SPI command to six different Gate Drivers?
Actually , we are trying to disable and enable all 6 six drivers in minimum time possible.
we are using independent slave configuration…
Part Number: UCC5870-Q1 Hello,
We are using the gate drivers in independent slave configuration.
Clock frequency 1 MHz.
We are facing some issue in synchronization of all 4 SPI lines. For instance, the MISO line is lagging from the Chip select pin by 2…

Figure 7-13 in the datasheet shows the CLAMP pin unconnected, should the wire running to the VEE2 pin go to the CLAMP pin instead?
(datasheet was accessed from https://www.ti.com/product/UCC5870-Q1 on 2022 Oct 25 and say "REVISED…
Part Number: UCC5870-Q1 We recently noticed that some of our gate drivers do not output 4V on the VREF pin. The configuration registers are setup to use the internal voltage reference.
We noticed that the parts that do not work have a leading "P" in the…
Part Number: UCC5870-Q1 hi experts
i have a question about ASC function and "Figure 7-27. ASC implementation Flowchart"
As shown in Figure 7-27,
Q1:whether can we configure UCC5870-Q1 when only VCC2 is up(VCC1 doesn't work)?
Q2: When VCC1…
Part Number: UCC5870-Q1 Hi experts
i have two questions about Rg
Q1: how to place Rg? close to OUTH/OUTL of IC or close to Power switch?
Q2: if Rg consists of multiple parallel resistors, what should i am careful about ?
pls share your comments.
additionally…
Part Number: UCC5870-Q1 We have previously implemented the use of the CRC_RX (CRCDATA register) in our system and that seems to work great.
Now we are trying to implement the CRC_TX (CRCDATA register) feature, which looked like it worked initially. However…

Hello,
We are trying to access the registers of gate driver ucc5870-q1 by sending the read /write commands through SPI communication, but no data is received back from the driver. I have shared the details, code and list of commands…
