Tool/software:

Hi expert,

My customer is looking for the low side switch and I want to promote TI's load switch. But there is a request from customer: the input and output of switch's MOSFET can be connected to GND. Do we have suitable devices can meet this request? Thanks.

Best Regards,

Ryker

Hello Ryker,

I am not quite sure about the requirements.

output can be connected to GND with some resistance. with-out resistance it will be shorted.

Do customer need short circuit protection and wake up into short ?

Thanks

Hi Amrit,

As we talked in Webex. Customer need Vin=0-12V load switch (auto grade), so I think TPS22810-Q1 is more suitable. Could you help to confirm if it can work with VIN<2.7V? Thanks.

Best Regards,

Ryker

Hello Ryker,

Sorry for the delay.

I have tested the device in LAB and discussed with design team on this.

Device will work fine for less than 0.3V than recommended operating condition which 1.6V for this device.

Below this voltage, device has not been validated or tested. It may shutdown at different operating temperatures.

Thanks

Hi Amrit,

Do we have device which can support 0V input voltage? Thanks.

Hello Ryker,

TPS22860 is the only 0V minimum input load switch.

TPS22992/7/9 are high current load switch with min VIN:0.1V

For auto grade TPS22996H-Q1 has min VIN of 0.6V

Thanks

Amrit
