Part Number: LM5105 Why is latchup not a concern, when operated within spec max.? I am concerned with cosmic ray induced latchup and not electrical latchup.
Part Number: LM5105 Other Parts Discussed in Thread: CSD87588N , , CSD87333Q3D , CSD88584Q5DC , CSD87353Q5D , CSD87334Q3D I am investigating using 2 of the LM5105 half bridge gate drivers for a full bridge coil drive circuit (see schematic sketch). For…
Hi Dong,
When I download the OrCad/pspice project from www.ti.com/.../snvm166 , it runs ok.
Also, when I look the error that you have there, it means the .SUBCKT definition of xdeadtimer is not recognized.
There are several things here:
1. What…
Sorry for answering that late, but I had a quite stressful week.
We also did a little bit of examination and found out the following. There is a normal dead time if the pwm is between 5 to 90 %. But if you reach about 94% the dead time suddenly disappears…
Part Number: LM5105 Other Parts Discussed in Thread: SN6501 We are trying to use the LM5105 to drive two N channel FETS that will control the 50V B+ to the drain of a RF power GAN transistor. We chose this IC, due to ability to quickly turn on and off…
Hi Marcel,
Thanks for your interest in our devices, and welcome to e2e!
This problem in the LM5113 is due to its lower operating voltage for GaN. Sine the LM5105 has a higher voltage rating, the issue doesn't effect the the LM5105 or other LM51xx…
I also have experience using the LM5105 in a solar battery charging circuit. For anyone else who happens upon this thread, here are some suggestions based on the circuit in the solarpower.docx schematic. Run the LM5105 Enable pin from the microcontroller…
Other Parts Discussed in Thread: LM5105 Hi
We are evaluating LM5105SDX/NOPB and we are facing the problem that the datatime DT1 and DT2 are not the same.
We attached the image.

According to tha datasheet, MDT is 50ns(typ…
Other Parts Discussed in Thread: LM5105 Hi all Would you mind if we ask LM5105? <Question1> As the operation of HO-Driver and LO-Driver, there are only Sink and Source mode. Is there Hi-z mode? As our recogniton, we think it doesn't exist .Is our recognition…
Hi Tim,
Is the 10K from the HO pin to ground/0V?
Do you have some of the devices where the HO/HS voltage has crept up to the higher level and is capable of driving th 10K resistor, if so can you send them back for FA?
If you remove the "bad" LM5105…
