VR5510

[zafeerferoz]

Hi , 

We are developing a design based on S32K314 with VR5510 as the PMIC. There are two PWRON1 and ON2 pins mentioned in the document as Wake up. Can we use this pin only for the Wake up application. Mainly PWRON1 for an Ignition detect and PWRON2 for Wake up INH for the LIN or CAN. 

Regards

Hi Guofred, 

Thanks for the reply. Why we went with VR5510 is we have additional 3v8 @2A for a 4G module. 

Wrt to the PWRON1 and PWRON2 pins - In the below Table 81 - it is mentioned as these pin can be configured as Wake up event. Hope we can use like this

Hi @zafeerferoz ,

Thanks for sharing the information, hope you goes well. 

yes, the hardware shows 2x input pin for wake-up detection.

may be we can check it again by using your development board. thanks.

Hi @zafeerferoz 

1)  i think the NXP PMIC FS65/FS26 is more suitable for S32K3 

2)  about the VR5510 PWRON1 and PWRON2, the reference as below. thanks.
