LM5060-Q1: Reverse Polarity Protection - Verification

Fabio Sponticcia1

Part Number: LM5060-Q1
Other Parts Discussed in Thread: LM5069

Hi, I'm planning to use the LM5060-Q1 in a 24V automotive application as surge stopper with reverse polarity protection (ISO 7637-2).
I found on this forum the possibility to implement the circuit shown in SNVA683 (https://e2e.ti.com/support/power-management/f/196/t/867979?keyMatch=SURGE%20STOPPER%20AUTOMOTIVE&tisearch=Search-EN-everything) . This application note is for the LM5069 and not for the LM5060-Q1, the two devices have some differences(abs voltage, SENSE and VOUT pins...):
Is the schematic attached correct? I "mixed" the result from TI spreadsheet (attached) and the link above.

Regards

Fabio

Hi Fabio,

I suggest to use LM7480x-Q1 as it offers better performance in meeting automotive transients.

If you wish to proceed with LM5060-Q1, please refer circuit configuration in https://www.ti.com/tool/TIDA-01167 the GATE circuit needs to be modified and it is discussed in LM5060-Q1 datasheet.

Best Regards, Rakesh

Hi Rakesh,

Many thanks for your answer.

LM7480x-Q1 was my first option, do you know when it will be released? I opened a TI case but I have not received any answer and my time is running out.

Regards

Fabio
