Part Number: LM7480-Q1 if battery system is 48V, how to select TVS specifications?
Are there any other points to note?
This redundant system will carry 1KW output. Please share your experiences for me. Thank you so much.

I am currently designing a protection circuit for our device. Our device operate at 48V with output current of around 8A We would like to protect it from:…
Part Number: LM7480 Other Parts Discussed in Thread: LM5069 , TIDA-010242 , Hi
We are currently evaluating your MIL-STD-1275E reference design (TIDA-010242 based on LM7480-Q1 and LM5069).
However, our system requirement is significantly higher:

LM74800 Questions
1. Why does HGATE take so long to start after the ENABLE action (approximately 4.8ms)? Is this defined in the spec?
2. When the input is reversed and reverse protection occurs, DGATE shuts down. Is HGATE…
Part Number: LM7480-Q1 Other Parts Discussed in Thread: TINA-TI Tool/software: Hello teams,
I download the PSpice file of LM74800, but I found the voltage of DGATE is not meet datasheet.
VIn is 12V ,but DGATE is 18V.
BTW ,how can i get the PSpice…
Part Number: LM7480 Tool/software: Hi, Attached please find Q10 (HGATE driven) VGS signal when load = 20A. I would expect an almost DC signal to fully enhance the FET (I understand the DGATE driven FET is linearly regulated to ~ 10,5mV voltage drop).…
Part Number: LM7480-Q1 Tool/software: Hi
I have a problem with the LM7480-Q1 failing to switch on the external transistors Q1 and Q2 in the circuit below.
The measured voltage on VS (pin 10) is approximately 3V referenced to GND. Input voltage is…
Part Number: LM7480 Good afternoon,
I have used the LM74801QDRRRQ1 in the past with success, however, I have a new design with it that is a little bit different. I have experienced a failure and would like to request a schematic review.
The application…

Hi,
V(DGATE) – V(A) only 3V, Causing Q1 to heat up.
The customer tested with 30V, VDGATE 33V,HGATE 41V, Q1 heat up,Q2 normal.
Increasing the capacitance CAP to 470nF does not improve either.
Part Number: LM7480 Tool/software: Hello -
We are considering using the LM74800 for a power MUX application, I found two diagrams illustrating how the OR'ing for this part:
In our application, we have four power sources
