TPS63001: Need help to apply logic on EN pin

Hi Gaurav,

What kind feature do you want for your application? device start switching once Vin applied?

Tao

Hi Tao,

When the charging USB cable is plugged in.

I would like to cut off power to the DC/DC converter. I would like to prevent battery usage while charging for safety reasons so that the battery is charging with the power to the DC/DC converter and therefore the rest of the functional components on the pcb cut off.

How can we implement this without any mechanical switch?

Thanks,

Gaurav

HI   Gaurav,

Got it, yes, you can disable device by pull the voltage level of EN to low by a MCU. That is totally ok for this device.

Hi Tao,

Thanks for your support and feedback.

We dropped this plan and will make EN high all the time.

Also, add LDO after TPS63001 to make noise free and stable 3.3 for MCU and ADC.

Please review below schematic and provide your feedback if any improvement is required for it.

Thanks,

Hi  Gaurav,

No commments for your schmatic, if can, could you share me you BOM and layout for further check?

can i consider "OK" for schematic?

I am on paper and pen stage. there is no BOM and layout. We will do it later.

Thanks,

Gaurav

Yes, i mean ok for your schematic

Thanks for your support.

please share your final design files including BOM and layout if you want me to double check.

Sure, i will post a separate thread soon.

Thanks,
