Part Number: UCD7138 Other Parts Discussed in Thread: UCC24612 Hi Team,
Customer used UCD7138, they would like to know whether PGND should connect with source pin or Kelvin source pin of MOS, if they want to get a more accuracy Vds detection. Thanks…
Part Number: UCD7138 Hi Team,
Customer used UCD7138 with a corner issue, and will not always appear, could you please help take a look here? Thanks in advance.
Background:
During no-load burst-mode operation, VCC hovers around 9V—well above the…
Part Number: UCD7138 Hi Team,
Customer used UCD7138 in LLC SR side, but found there is an issue that the power supply of UCD7138(VCC 12V) has a abnormal voltage drop, and noticed that the reason is supply current reaches 200mA for each UCD7138 board…
Part Number: UCD7138 Tool/software: Hi Team,
Customer ask that whether UCD7138 has next Gen? The VCC is not enough for SiC MOS and VD is not enough for 48V server PSU. The competitor is like NCP4306. Please feel free to contact me, thanks.
BRs,

Hi Team,
Customer uses UCD7138 in 800V HVDC LLC SR, as a SR controller.
He would like to know whether we have a better soluion for this 800V bus. 1000V Si FET is not common, and SiC FET…
Part Number: UCD7138
Hello,
I am working on LLC converter design where UCD7138DRST is used as gate driver for synchronous MOSFETs (two in parallel).
I have disabled DTC input and also grounded the CTRL pin externally so PWM output is in line with…
Part Number: UCD7138 Tool/software: Hello, would it be possible to get a SPICE model for the UCD7138 that is usable in KiCAD's integrated NGSpice? The published, encrypted PSpice model doesn't work.
I am trying to drive a GaN HEMT with this driver,…
Part Number: UCD7138 Tool/software: Hi all,
I have been researching the LLC SR driver. I've read the datasheet of UCD7138, and I have a question.
In "8.2 Functional Block Diagram (P.11)", there is an OR gate. It ORs the Q and comparator output, and…
Part Number: UCD7138 Dear Sir,
I want to use UCD7138 for my application which has MOSFET VDS as 150V max ( IPP076N15N5AKSA1 ).
Can i use this driver W/O VD pin ?
If not , can you please suggest alternate PN for 150V bus volt?
Part Number: UCD7138 I want to use UCD7138 in 400V Mos drive，I use a 650V low current MOS to block VD，but this MOS‘s turn off time longer than main MOS turn on time，whether this will destroy UCD7138？If yes，How can I use ucd7138 in this condition？
