Hi,

My question is it possible to use /MRST pin of the bq78350 to trigger an external reset from an MCU?

My plan is to put in series a 1k resistor from the /MRST pin to the MCU.

Thanks,

Andras

Hello Andras,

this pin is used to reset the device via external signal when pull low, be noticed that it need to pull high in normal status.

Thank you

Hi Andras,

Yes, that is possible, but be careful to follow the recommendations in section 11 of the datasheet regarding this pin. This pin is sensitive to noise and you will want to avoid unwanted resets.

Best regards,

Matt
