Part Number: TPS38-Q1

Would you let me know about internal sink current and pullup resistance value for CTRx/ /MR pin?

(Is pullup resistance value 1000kΩ_typ, correct?)

I want to know required sink current for internal FET set certainly Low on CTRx/ /MR pin.

Best regards,

Hi Satoshi,

The internal resistance for the CTR pin is 1000kΩ.

Just for clarification, you are using this pin for its MR functionality? Are you going to utilize the CTR functionality as well?

Hi Jesse

In this use case is Manual Reset functionality.

Does MR and CTR have different characteristics?

If yes, would you let me know both cases?

Best regards,

Satoshi

Hi Satoshi,

Thank you for your patience, according to our design team, the internal FET pulls down at roughly 250uA, for both CTR and MR functionality.
