TFTs / NHD-2.4-240320CF-CTXI#-F spec on VDDIO
« on: November 19, 2016, 01:31:27 PM »
I want to use the NHD-2.4-240320CF-CTXI#-F in a battery application.  The uP and VDDIO connected to the battery and VDD connected to a charge pump controlled by the uP.  When the unit is off, the uP turns off the charge pump and goes to sleep.  Can VDDIO be left powered while VDD is off?  What is the current draw on VDDIO if it were left powered?
