Part Number: UCC5870-Q1 Hi,
I understand that the drive-strength can be altered in steps of 1/6 (so, 1/6, 2/6, 3/6, 4/6, 5/6 & 6/6) by appropriate binary values programmed into CFG8 register bits 0 to 2. The datasheet states that this “on the fly…
Part Number: UCC5870-Q1 Hi expert
Customer wants to use conformal coating on PCB(UCC5870-Q1 on this PCB).
If in this situation, how to calculate clearance and creepage.
pls share your comments .
Hi Sherry,
Thanks for your questions. I have included responses below:
Sherry Liang said: For GM fault, if the customer sets tGMBLK=4000ns, the first pulse width is only 3us followed by 2us dead time. Will this condition report GM fault?
No, this will not…
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
We know that the drive-strength can be altered in steps of 1/6 (so, 1/6, 2/6, 3/6, 4/6, 5/6 & 6/6) by appropriate binary values programmed into CFG8 register bits 0 to 2. The datasheet states that this “on the fly” feature…
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 We are using the UCC5870-Q1 IC for driving high power IGBT's.
Can the VCECLP (Pin 34) on the UCC5870-Q1 be left unconnected (or connected to ground) if the VCECLP functionality is not going to be used?
Regards
Scott
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 Our customer is having an issue with triggering the secondary side ASC (AI5 & AI6) with no voltage on VCC1 (never applying voltage to anything on primary side). These are the voltages that they are applying to the secondary/isolated…
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
