Part Number: TPS28225 Other Parts Discussed in Thread: LM2105 , UCC27211A Hello everyone,
I'm designing a Peltier cell controller circuit, and I'll be using a full H-bridge for this purpose. I will control the gate signals of the MOSFETs with a 200kHz…
Hello,
The LMG1210 can drive GaNFETs in parallel but be aware that with each additional FET, the total gate charge Qg will increase. This will affect the power dissipation, which may result in having to use a lower switching frequency than desired,…
Hey Ryker,
Thank you for reaching out with your question regarding the LM5109B.
Yes, the LM5109B is capable of driving three MOSFETs in parallel. The drive current requirements are dictated by the desired rise/fall time, total Qg of the FETs being…
Hey Joaquim,
Unfortunately our lowest BDC motor drivers require 1.65V minimum. Here are all of them: https://www.ti.com/motor-drivers/brushed-dc-bdc-drivers/products.html#358min=1.65%3B1.65& Our gate drivers all require the gate driver VM power supply…
Hi Chuanfei,
A full-bridge topology will usually require half-bridge drivers. There is a way to drive an LLC using a low-side with a pulse transformer like this:
However, I think a half-bridge will be better for you here. For 60V bus voltage, I…
Hey Patrick,
Thank you for your question regarding the LMG1210.
For the output stages of the high-side and low-side of the driver, there is an internal pull-down FET that would connect HO to HS and LO to VSS. This internal pull-down FET's impedance…
Hi Andrew,
Thank you for reaching out! LM5106 takes a single input and generates a complementary output signal. The programmable dead time of LM5106 can be configured to optimize the rising edge delay for the gate driver outputs. This will work for…
Other Parts Discussed in Thread: UCC25800 Most applications including power delivery for industrial and automotive utilizing a half-bridge gate driver use the bootstrap diode and boot capacitor to generate the high side driver bias. This is the simplest…
Part Number: UCC27311A-Q1
Tool/software:
What are the considerations for using the high-side output of a half-bridge gate driver as a low-side gate driver?
When utilizing a half-bridge driver in a typical half-bridge configuration, an internal level…
