Hello,
I am designing a custom board using i.MX93 and PCA9451. On the EVK, I noticed that the ONOFF pin is connected to a push button for power control.
In my design, I would like to use a slide switch instead of a push button for power control. Could you provide any design examples for this approach, or explain how it should be implemented?
Here is my current idea:
- Pull up the ONOFF pin of i.MX93 to the power rail.
- Leave the PMIC_ON_REQ output of i.MX93 floating, and connect the slide switch to the PMIC_ON_REQ input of PCA9451.
- Connect the PMIC_STBY_REQ output of i.MX93 to PCA9451.
Any guidance or recommendations would be greatly appreciated.
Thank you for your support.
Best regards,
tkato
