My project use a Jetson TK1, connected to a 10" Universal LCD with HDMI Interface and capacitive multi-touch. These are powered from Li-PO 2200mAh battery. To protect the battery life (display and his back-light have an appreciable consumption!) I want to interrupt the connection from battery of 11.7V, after that the system is shutdown (enter in deep mode). I think is possible to use the signal SATA_PWR__EN_T124 (this breaks off the +12V from SATA POWER connector)to do my intention. My question is: where can I find the all power signal diagrams in shutdown moment? I find some of these diagrams (SATA_PWR_EN_T124 isn’t through them), but only as Power-Up Sequence (see Tegra K1_Embedded_DG_v03.pdf)
I will appreciate any useful answer and piece of advice.
Thank you very much,
