Hello Saravana,

The BQ25750 does not have built-in reverse polarity protection.

Will this work for your application? Let me know if you have any questions about this.

Best Regards,
Ethan Galloway

Hello Ethan,

Yes, may be we need to have external protection.

Hello Saravana,

Got it. If your system can't use a diode to protect against reverse polarity, you may want to ask a new question for the E-Fuse team to get suggestions for E-fuses to protect against reverse polarity.

Let me know if you have any other questions.

Best Regards,
