Hello team,
Hope you are well.
Also, would you be able to help out with customer question below:
LM5175 act as a front-end stop start device and the LM7461 as our reverse battery protection IC.
Power source would be standard lead acid battery (12V).
Operating from 6V, ideally able to operate down to 4.5V at the LM5175 up to 36V*.
*9Vmin nominally <9V for jump start and stop-start
*nominally up to 13.5Vdc
*up to 24Vdc for 1 minute
*up to 36V for spurious induce pulses
* survive up to 42V
*Expect LM5175 to source up to 5A
With a 12Vnom input at up to 5A (through an external 5A fuse) handle current monitoring to reduce load as the input current increases while input voltage dips.
There will be transient protection prior to the LM5175 and will include a separate energy well.
Questions:
Will regard to an energy well, what is the effect on an LM5175 output if the input power drops below UVLO and an in line bulk capacitor (470uF to 1mF) holds up the LM5175 output?
With the LM5175 soft-start in mind, can the LM5175 turn on into a 1mF load?
Note:
I looked to see if this issue has been responded before and located an e2e post under 'LM5175 unstable issue' that is still open.
Regards,
Randhir
