Need sense and current details

Udaya on Dec 2, 2025

Category: Hardware

Product Number: LTC4365

Iam using this IC for voltage control and reverse polarity circuit.

I required to limit current by 15A ,can i do that in this IC or need extra circuit.

6V to 16V and 15A is the requirement with reverse polarity.

kindly help me out this any sugestion.

The LTC4365 has no sense resistor and cannot monitor the current.
Use the LTC4368.

Thanks Ashapiro .It worked .

But I designed for 15A .If 15A exceeds it is not fully zero.It is showing impulse .

You are basically doing start-up into a soft short with a resettable e-fuse. (Reset time set by C3 cycling 32 times).
V_OUT rises to 7.5V and drops because that's when it trips overcurrent (7.5V/0.5Ω=15A).
Part behaves as intended.
