Hi team,

Customer is asking the status of below constant current circuit when PTC and PTCEN are connected to VSS. Will the constant current circuit still be sinking current when PTC and PTCEN are connected to VSS? Thanks.

Hello Hollis,

I believe when both PTCEN and PTC are connected to VSS then the current source is also shutdown, let me verify this.

Sincerely,

Wyatt Keller

Hollis,

I verified the current source is disabled when both PTCEN and PTC are connected to VSS.
