Part Number: LM5109A Other Parts Discussed in Thread: LM5109 , , UCC27712 , LM5109B Hi I'm planning on using the LM5109A to drive a couple of low Rdson MOSFETs. The two MOSFETs are configured to drive a solenoid from automotive voltages. Solenoid manufacturer…
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…
Part Number: LM5109B Other Parts Discussed in Thread: LM5109A Hello,
Today we are using LM5109A, but we might change to LM5109B.
What is the main different between these parts? They seems very similar for me.
Only different I see is that LM5109B…
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…
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…
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…
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 the…
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…
