Part Number: TLV62085
Other Parts Discussed in Thread: TPS62810, TPS62810-Q1

I have two questions about EN of TLV62085.

1.Does this device have hysteresis at EN?

2.Are there the restriction about slew rate of EN?

Hi Yokota,
1. the EN pin is a logic input with hysteresis.
2. Not that I am aware of. the only thing is you cannot get a precise enable time in this device. If you want a precise enable delay time you can take a look at the TPS62810

Hi Sabrina-san

Thank you for the reply.

Please let me confirm you just in case.

1.Could you tell me the specific value of hysteresis at EN?

2.May I understand that TLV62085's enable time is about same time of TPS62810-Q1?

Best regards,

Yokota

Hi Yokota-san

The specific value of hysteresis in not available. TLV62085 and TPS62810 are two different devices. you can not use the spec one for the other
What is the target application? what is the main concern regarding the EN?

Hi Sabrina-san

The application is building automation.
I concern the operation the following case.

・Inputted the slow signal at EN
・Inputted the signal around 1V at EN

Best regards,

As you can read in this post : e2e.ti.com/.../760071. Building a RC enable delay circuit is ok.
the converter will get enabled at a point between 0.4V and 1V. the internal circuit design does not allow the converter to be on and off at the same time. Above 1V it would always stay enabled.

Sabrina
