Hi Omer,
In addition to Ben's reply - you can consider TI's reverse polarity protection devices - the LM7450x-Q1 family should be a good starting point for you - ( https://www.ti.com/product/LM74500-Q1) . You can also look at the https://www.ti.com…
Part Number: LM74700-Q1 Other Parts Discussed in Thread: LM74500-Q1 Tool/software: Hello, I have a few questions to consult
1. Is it necessary not to place RG?
2. Does the anti-reverse circuit in the red box not need to be connected, and there is…
Part Number: LM7481-Q1 Other Parts Discussed in Thread: LM74500-Q1 , LM74501-Q1 , LM74502-Q1 Hi
Could you help suggest a reverse polarity protection IC for the input terminal.
The requirements are as follows:
Input power: 1000w Input
voltage:…
Hi Carlo,
Yes, you can add LM74500-Q1 infront of EFUSE. OR if only requirement from EFUSE is inrush current control, you can consider LM74502-Q1 which offers inrush current control.

Hi Federico,
In that case, please look at the block diagram below.
Buck is protected from reverse polarity by LM74500-Q1.
Batteries and BUCK are ORed for redundant supply.
Batteries can be charged by BUCK by toggling the MODE pin and enabling…

Thanks and Regards…
Part Number: LM5050-1 Other Parts Discussed in Thread: LM74500-Q1 Hi Team,
can you help with the following customer question:
We already found LM5050 really suitable for our requirements, but sadly there is an unpleasant feature with this chip…
Part Number: LM7481 Other Parts Discussed in Thread: LM7480-Q1 , LM74700-Q1 , LM74500-Q1 , LM74800-Q1 Hi Team
There is a 48V bus, and a 48V PSU. I'm looking for an oring solution. When the 48V bus is on, the system is powered by the 48V bus, otherwise…
Hi Ben,
Looks like you are dissipating the excess energy during regenerative mode in the brake resistor R1.
Is there any problem if you feed this excess energy back into the battery ? if it is acceptable then using LM74500-Q1 (which is nothing but…
Part Number: LM74502 Other Parts Discussed in Thread: LM74500-Q1 Hello,
My question was already asked on this forum but I would like to confirm. I would like to use this chip in reverse battery protection mode ( don't need back to back MOSFETs to…
