Part Number: LM5108 Tool/software: Hi ，I want to use LM5108 to drive N-MOS, do I have to use " Photo Coupler isolation" between MCU(which generates PWM signal) and LM5108? WHY? thanks
Part Number: LM5108 Tool/software: Dear teams,
When I use this IC (LM5108), I found that the driving current will be increased with the load current, but actually it could not be changed and the switching frequency is the same.
Is there any reason to…
Other Parts Discussed in Thread: LM5108 Tool/software: Hi expert,
For LM5108, my customer meet voltage bounce on HO under first time LO give the PWM. which is the bootstrap cap charging,
Here is the waveform, CH4 :low side Vgs, CH3: high side Vgs, and…
Part Number: LM5108 Hi expert,
My customer wants to know whether LM5108 has internal pull down resistor.
if the answer is yes, how about the pull down resistance?
they want to see whether they can not put external pull down resistor to save the BOM cost…
Part Number: LM5108 hi team,
Here are some questions from customers,could you please help me to figure out these?
1. Does the internal bootstrap link of LM5108 have a current-limiting design? If so, please help confirm the current limit value and provide…
Part Number: LM5108 Hi Team,
Our customer has some question about LM5108.
How to design the current capability of the power supply VDD of the LM5108 driver chip? According to calculations, at startup, the instantaneous current of VDD is related to the…
Part Number: LM5108 Here is the question from my customer. Please help on this.
In the example board layout of LM5108DRCR, there are 4 holes Φ 0.2 on the big pad. Does it mean it’s better to place the holes on the big pad as symmetrically as possible…
Part Number: LM5108 Other Parts Discussed in Thread: TMUX8108 , Dear,
Is it possible to use this gate driver as a single channel gate driver?
We have the following situation. We need to act as an electronic switch between a high impedant input and a relative…
Part Number: LM5108 Hi,
I am currently working on the power control PCB for a FOC controlled BLDC motor. The three phases of the motor are powered using three LM5108 coupled to 6 MOSFETs (1 LM5108 + 2 half bridge MOSFET per phase). PWMs are generated…
Part Number: LM5108 Other Parts Discussed in Thread: LMG1205 , LMG1210 , LM5113-Q1 Hi Team,
Can LM5108 drive the GaN FET? If so, what's the external circuit need to be added to drive the GaN FET? Thank you.
Sincerely
Frank
