Other Parts Discussed in Thread: LM5109A , DCH010515S , LM5112 , UCC27517A Hello community,
I am using the LM5109A in a step down converter. I experienced a situation where the LM5109A is not switching within tens of nanoseconds as it should but takes more…
Other Parts Discussed in Thread: LM5109B , LM5109A Dear TI Sir:
I have a question for LM5109A and LM5109B that is LM5109A/B have Cross Conduction Prevent Logic Function?
When the timing or logic of HI and LI are wrong, LM5109A/B can tuen off HO and LO to…
Other Parts Discussed in Thread: LM5101 , LM5109A Hi Team,
Customer would like to manually keep high side FET on in order to achieve 100% duty cycle during certain scenarios. Customer is already able to do this with LM5101; we just want to make sure the…
Other Parts Discussed in Thread: LM5109B , LM5109A Hi, does anyone know the difference between LM5109A & LM5109B? Thanks a lot.
I compared the datasheet and can't find any difference....
Hello Ben,
I understand the pin compatible consideration. One driver to consider that has an SOIC8 pin compatible package and also a SON package with lower thermal resistance is the LM5109A. This part however does not have the interlock and dead time…
Hello Evan,
For the 1st question you asked there is an improvement to the LM5109B from the LM5109A. The change to the LM5109B guarantees that in the case of the VDD falling below the operating point the high side driver is guaranteed to be forced to a…
Other Parts Discussed in Thread: LM5109A What does the LM5109A/B output stage look like? Is it a bipolar or MOS driver? What type of transistors are used for the pull up and pull down? I could not find this in the datasheet.
Many thanks,
Toby
Part Number: LM5109B Other Parts Discussed in Thread: LM5109A , Hello,
In chapter 7.3.1 it says:
"Any UVLO condition on the bootstrap capacitor (VHB–HS) will only disable the high-side output (HO)."
What does disabled mean? That the HO will…
Other Parts Discussed in Thread: LM5109A I’m looking for help determining what gate driver will work with a particular MOSFET. Maybe an application note with examples? I’m considering using CSD19536KTTT with LM5109A but I’m not sure how to calculate…
Part Number: TXB0102 Other Parts Discussed in Thread: LM5109A Hi Everyone,
Can anyone help me with the problem I am having using TXB0102 to drive CSD16321 N-channel FET please.
I need 5V to drive the gate of CSD16321 FET, so I am using TXB0102 to Level…
