TPS272C45: function check and automotive grade solution

Hi YiChi,

Thanks for your prompt reply!

It looks like TPS2HB50-Q1 is almost the same function like TPS272C45 am I right?

I will promote it to customer, and then feedback to you later, thanks!

Hi Yichi,

Does we have same function but have lower current limit solution ? Automotive grade is necessary.

Customer just need 10mA Imax, they think if the current limit is 100mA is the best, 0.5A~1A is the Maximum they can accept.

Thank you !

Hi Yichi,

Sorry, customer prefer separate EN pin.

Their output have different logic.

Maximum OCP value can accept up to 1A.

Do you have any better suitable solution?

Thank you~

Kai

Hi Yichi, 

No customer need separate EN pin not IN input.

And by the way, does our power switch had reverse current protect inside?

Hi Yichi,
Oh, so the in1 & 2 is output independently to out1 & 2.   

Sorry I didn't noted it!

1. So the Enable pin here will control both channel 1 & 2 at the same time?
   Customer can add 10V at VS pin(TPS2H160-Q1), and add different 3.3V PWM signal to IN1 & IN2, out1&2 will output 10V PWM independently right?
   
   
2. The minimum current limit can be set with TPS2H160-Q1 is 0.5A ; TPS2H000-Q1 is 0.1A?
   But why the TPS2H160-Q1 shown Figure 18. Current-Limit Ratio at 0.25 A in the datasheet?
   It can set at 0.25A but we don't suggest?

Thank you 

Kai
